...Sorry guys i forgot to scribe for last Friday and its been a few days now... i would tell my side of the story, however that would take up you time and mine and we don't want to waste time.
Anyways! On Friday we had a substitute named Mrs Zulak. She wasn't every helpful and i think she didn't know anything about physics so lets not talk about her anymore. We were asked to read pages 110 to 119. Then answer questions one to seven on page 129.
Yeah.. it was a pretty slack day so there isn't much to say except to say sorry because i forgot to scribe even though i had a lot of time.
And i didn't really pick the next scribe because Mrs Kozoriz picked for me. I wanted to pick a scribe and blackmail them if they didn't wanna scribe but my plan failed.
Sorry for not scribing! forgive me!
-Roger out...

More on Kinematics...
Hello :)
Thanks to Roger (-_-), I am now your scribe for today.
If you recall last Friday, we worked on some problems/questions from the book. Today, we corrected numbers 1-7 on Page 129. We also corrected Study Guide 4.2: Components of Vectors.
Here are the answers...
PAGE 129 #'s 1-7
1.) 65N - 32N = 33N [E]
2.)
a. vector D and vector C: ----------> 10 units
b. vector A and vector D: -> 1 unit
c. vector C and vector A: ---> 3 units
d. vector A and vector C: ---> 3 units
e. vector E and F: no vector or a "." (dot)
3.)
a. 100N - 75N = 25N [up]
b. 100 + 75N = 175N [down]
4.)
a. 200km/h + 50km/h = 250km/h
b. 200km/h - 50km/h = 150km/h
5.)
a. vector C and D: *I think there was a mistake on this one in the book, but I didn't get to write it down :(*
b. vector C and E:
x=10.63
c. vector D and E:
x=8.7
6.)
a. A+C+D: -------> 7 units
b. D+E+B:
c. B+D+F: zero
STUDY GUIDE 4.2: COMPONENTS OF VECTORS
1.) b
2.) b
3.) c
4.) b
5.) d
6.) a
7.) c
8.) c or b
9.) b or c
10.) c
11.) c
12.) c
13.) c
14.) c
Sorry if some of the answers that I put here are incorrect. Just ask our fellow classmates if you think that the answer is really off.
After the corrections, we were given a handout about Constant Velocity and Constant Acceleration. Ms. Kozoriz explained what "constant" meant.
constant = uniform = same = never changes
Constant Velocity is a velocity that always stays the same.
Constant Acceleration can also mean Changing Velocity.
She also told us the alternate formulas for constant velocity and constant acceleration.
Constant velocity
delta d = velocity * delta t

Constant Acceleration
acceleration = (V1- V2)/(delta t)
displacement = ( (V1+V2)/2 ) * (delta t)
After that, we had the rest of the class time to work on new worksheets. One was to practice using the formulas with problems. Another was sketching motions in graphs.
I don't really do well on explaining things, so pardon my lack of information (-_-")
That's all for now. I hope that I stated enough everything that happened in class today.
*edit: Almost forgot, the next scribe will be Moot a.k.a. Fajipico. Chyeaha :)

YOSHA!
This is Cloud Strife...let's get this started and get straight to the point. First of all, we handed in the Appendix 3.8 worksheet so if you haven't gotten it in yet, i suggest you check with Ms or Mrs Kozoriz (whichever one it is). We also corrected study guides #4 and 5.
Here are the answers for study guide 4:
1) 6 km
2) 6 km
3) 6 km
4) 4 km
5) 3 km
6) 5 km
7) 40 m
8) 12 km
9) 20 m
10) 500 m
11) b
12) d
13) b, f, h
14) b, f, g, i
15) b, f
16) true
17) protractor
18) tail
19) true
20) not dependent
Study Guide 5:
1) position = y-axis, time = x-axis
2) it is at the same position
3) object is at rest
4) not a finite period of time
5) 0s.
6) a
7) d
8) b
9) b
10) a
11) c
12) --> --> -->
13) . . .
14) <-- <-- <--
15) four
16) true
17) d
18) true
19) true
TABLE 1
A) 0.25 km/min 10 min 25 km
B) 0 km/min 7 min 0 km
C) 0.4 km/min 13 min 5.2 km
TABLE 2
30 min 7.7 km 7.7 km 0.26km
Thats it for the corrected worksheets. Sorry if any of the answers are incorrect. I wasn't in class for a small portion of the class so i needed to check the answers with a friend. I think we were also doing some notes or at least a review on component or resultant vectors. Unfortunately, I was unable to completely compy the notes correctly (and i dont know how to do anything on this, but type). Therefore, I suggest you go ask your friends or fellow classmates in order to obtain the small portion of notes.
Finally, nearing the end of class we were also given 2 sheets to work on:
- 4: Study Guide ... Section 4.2: Components of Vectors
- Simple Vectors
There was no due date given to finish these worksheets, but we're more than likely going to be correcting it soon, so i suggest everyone gets it finished ASAP.
That's all for the scribe today. The next scribe will be
ROGER CATIPON.
I don't know how to check his username on the editing screen so I'll just leave it like that.

Quick Recap! (:
Okay so this blog has officially been forgotten...sadly...LOL! So I guess for now, since no one is really willing to do it at the moment, I'll try my best to update this blog. Here we go!
Monday November 10
Hmm....what did happen this day? We corrected a worksheet? Hmm....yea I think that's what happened. The unit of Nature of Light Part 2 was starting to come to a quick end.
Tuesday November 11
Honestly? I have no idea what we did. But we probably corrected some more questions? Ohh man my memory is horrible! Please forgive me. -_-"
~edit~
HAAH oh yea I forgot we had no school that day. Wow I overthought this....
Wednesday November 12
Okay I at least remember what happened this day. We reviewed everything we needed to know for the test for the next day.
Thursday November 13
We had the Nature of Light Part 2 test. Enough said. This unit is DONE!
Friday November 14
We corrected the tests? Yea I think that's what happened. Also I believe we started what is now the current unit: KINEMATICS. We had to read basically the entire white booklet she gaves us and we also had a couple practice worksheets and one worksheet to hand in. Gaah I feel so bad. I don't even know if the dates are correct.
Monday November 17
We did a lab with motion sensors (which was pretty amusing I thought). Basically, we had to recreate four distance-time (position-time) graphs that Ms.K put on the board and then we had to make up our own. We used these little graphing machines, which I forgot the name of, to do this. The Smart Board was also available. We also got some worksheets which consisted of two work booklets and a fill in the blank summary thing.
Tuesday November 18
We finished the lab from the previous day. We also had to label what we did to make each section of the graph. ex) If the line was straight, we stayed still in front of the motion sensor and if the line went up, we moved away from the sensor. We also had to make velocity-time graphs to complement the position-time graphs we made previously. For the rest of the class, we worked on the worksheets from yesterday. The only one that we have to hand from that bunch is one of the booklets. I forgot what it's called (3.8?) but the first page has a graph and it's about a boy and his toy truck? Yeah it's about a boy and the motion of his toy truck. We have to hand that in on Thursday.
Wednesday November 19
Today Ms. Kozoriz wasn't here today so Ms. Karras came in her place. Today we went over the fill-in-the-blank summary type worksheet we got previously. Because I have nothing else do to (after I am here updating this, what else can I be doing at the moment?) I'll post the answers here in order:

Photoelectric effect & wave-particle duality
Konichiwa!!!
Watakushi-wa Mary Ararcon (Alarcon), desu.
Watakushi-wa Mary Ararcon (Alarcon), desu.
Yesterday (November 7), we did Young's Experiment Problems and "The Current Model of light: Wave- Particle Duality" . We've also tackled pages 22-26 on the green booklet.
If you guys missed yesterday's class, here are the solutions and answers on the experiment problems.......
first, here's the formula:
λ = (X) (d)
L
where:
λ = wavelength
X= distance between adjacent nodal lines
X= distance between adjacent nodal lines
d= separation between slits
L= perpendicular distance from the slits to the screen.
1)
λ = ?
d= 0.0190mm/ 1.9x10 -5m
L= .600m
λ = (0.0211m) (1.9x10 -5m)
.600m
λ = 6.68x10 -10 m/ 668nm
2)
λ = ?
X= 13.2 mm/ 0.0132m
d= 1.90x10 -5 m
L= .600m
λ = (0.0132m) (1.90x10 -5m)
.600m
λ = 4.18x10 -7m/ 4118nm
3)
λ = 596nm/ 5.96x10 -4mm
X=?
d= 1.90x10 -5m/ 0.019mm
L= 600mm
X = (5.96x10 -4mm) ( 600mm)
0.019mm
X = 18.8mm
4)
λ = 632.8nm/6.328x10 -7m)
X= 65.5mm/0.0655m
d= ?
L= 1.000m
d= (6.328x10 -7m) (1.000m)
0.0655m
d=9.66x10 -6 m
5)
λ = ?
X= 55.8mm/0.0558m
d= 9.66x10 -6m
L=1.000m
λ = (0.0558m) (9.66x10 -6m)
1.000m
λ =539nm
6)
λ =542nm/ 5.42x10 -7m
X= 4.00cm/ .04m
d= ?
L= 1.20m
d= (5.42x10 -7m) (1.20m)
.04m
d=1.63x10 -5m
7)
λ = v/f
λ =343m/s
325Hz
λ = 1.055m
X= ?
d= 4.0m
L= 4.5m
X= (1.055m) (4.5m)
4.om
X=1.18m/1.2m
If you are having a trouble reading the duality thighy,, I'm sorry..
I'll just type it for you,,
Particle model:
*Rectilineat Propagation
*Reflection
*Dispersion
*Photoelectric Effect
Both:
*Reflection
*Rectilinear Propagation
*Dispersion
Wave Model:
*RectilinearPropogation
*Reflection
*Refraction
*Dispersion
*Diffraction
*Partial Reflection and Partial Refraction
haish... it's now 6 am and I'm soooooo tired... I still have work tomorrow.. :(
well,,, for the last part,, just read pages 22-26 (green booklet)
Oh,, by the way,, if I'm not mistaken,, Ms. K will not be there on Monday..
Answer the question sheet because we will go over it on Monday..
We also have a test on Thursday...
Okay?!
Ganbatte ne? (Come on)
Aja Aja Fighting!!!!
Yours truly,,
Pretty Mary
and the next scribe is Wonderbread.... I'm sorry,, i don't know who you are. It's just that,,, your code name is cute... So,,, Good Luck...
Friday, November 7, 2008
Today in the beginning of class we basically just reviewed the notes we were supposed to copy off the board in the last 2 days...(Particle and Wave Theory of Light) But Mrs. K wrote it in a "simpler" way on the smart board...Here they are:
PARTICLE THEORY OF LIGHT
Scientist composed: NEWTON
Property easily explained by Particle Theory: Rectilinear Propagation (Travels in straight lines)
Reflection: angle of incidence = angle of reflection
Refraction: Light travels faster in water than air. (INCORRECT!!!)
Diagram of refraction:(below)
PARTICLE THEORY OF LIGHT
Scientist composed: NEWTON
Property easily explained by Particle Theory: Rectilinear Propagation (Travels in straight lines)
Reflection: angle of incidence = angle of reflection
Refraction: Light travels faster in water than air. (INCORRECT!!!)
Diagram of refraction:(below)
Dispersion: All colours of light have the same frequency. Wavelength x Velocity factors are different in each colour. --Wavelength of red is Largest
--Wavelength of violet is Smallest
Partial Reflection/Refraction: "Theory of Fits" Newton thoug
ht this was a weak explanation. Diagram-->
Diffraction: Particles interfered with the edges of a barrier (VERY weak explanation)
WAVE THEORY OF LIGHT
Scientist composed: HUGGENS
Property easily explained by wave theory of light: Each point is a new source for a wavelet to be created.(connect the wavelets & get a new wavefron
t)
Diagram---->>>>
Reflection: Angle of incidence = Angle of reflection
Refraction: Light slows down when entering water. (FOUCAULT showed that this happened)
Dispersion: (diagram below) (INCORRECT!!!)
Partial Reflection/Refraction: The Wave Theory is better able to explain this phenomenon than the Particle Theory.
Diffraction: Wavelength of light is very small. (GRIMALDI showed evidence for this)
Finally, near the middle of class we watched a video on youtube titled "YOUNG'S EXPERIMENT" and recieved MORE homework.
Finish questions 1-15. OMIT #2
and for extra practice...
Young's experiment problems.
I'M TIRED NOW...BYE GUYS!

Wave Theory of Light
WEDNESDAY, NOVEMBER 5, 2008
Appendix 2.4: Chart for Evaluating the Models of Light
MODEL: WAVE
Phenomena: Rectilinear Propagation
Supporting Arguments: every point on a wavefront can be considered as a point source of tiny secondary wavelets the spread out in front of the wave at the same speed.
Counter-Arguments: Newton said the the wave theory adequately explain Rec. Prop since waves emitted from a point source spread out in all direction.
Phenomena: Reflection
Supporting Arguments: Light reflects from a surface and the angle of incident is the same/equal to the angle of reflection.
Counter-Arguments: None
Phenomena: Refraction
Supporting Arguments: when wavefront move into shallow water they refract so that angle of refraction is less than the angle of incidence
Counter-Arguments: None
Phenomena: Dispersion
Supporting Arguments: Color of light have the same frequency but different wavelength.
Counter-Arguments: None
Phenomena: Diffraction
Supporting Arguments: When a large wavelength passes through a small opening you get a large diffraction and the opposite occur with a small wavelength and a large opening, wavelength of light very small.
Counter-Arguments: Newton said that if light was a wave should bend a lot more than the scientist Grimaldi observed.
Phenomena: partial reflection/ Refraction
Supporting arguments: waves partially effect/refract when there is a change in velocity partial reflection is noticeable when there is an increase in velocity partial reflection occurs when there is decrease in velocity.
Counter-arguments: None
Phenomena: Speed of Light
Supporting arguments: Wave theory shows that light slows down is a more dense medium (Foucault)

Hey guys, it’s been awhile. (:
During this period we worked on two sheets, "appendix 2.4: Chart for evaluating the models of light" and "contributions to the determination of the speed of light". Unfortunately, because of the Boo@DMCI pep-rally last Friday, we are a class behind. Either way, we are encouraged to work harder! ;D
--------------
Answers for Appendix 2.4: Chart for evaluating the models of light:
Phenomena: Rectilinear Propagation
Supporting arguments:
~Sunlight passes through clouds making straight lines.
~Sharp objects are cast
Counter-Arguments:
~None.
Phenomena:Reflection
Supporting arguments:
~very hard spheres collide with very hard surfaces and bounce off the same angle.
Counter-Arguments:
~none.
Phenomena:Refraction
Supporting arguments:
~When a ball rolls down a slip and continues on to a lower slope, the accelerating force causes the ball to change direction; resulting in a refraction.
Counter-Arguments:
~Speed of light in H2O is less than the speed of light in air.
Phenomena:Dispersion
Supporting arguments:
~each particle of a spectrum has a different mass. Violet refracted more than blue, so violet has small mass.
Counter-Arguments:
~All particles have the same mass.
Phenomena:Diffraction
Supporting arguments:
~Newton felt that the beam bending outward form a slit resulted from the interactions and collision between the light particles at the edge of the slits.
Counter-Arguments:
~Grnaldi showed that a beam of light passing through a successive narrow slits produced on a screen, a band of light slightly larger than the width of the slits.
Phenomena:Partial reflection/refraction
Supporting arguments:
~Newton proposed the “theory of fits”. “Fit” for easy reflection
Counter-Arguments:
~How does a particle know about what is good “fit”?
Phenomena:Speed of light
Supporting arguments:
~Light moves quickly in a dense medium.
Counter-Arguments:
~The opposite is true, light moves slower in a dense medium.
---------------
As for the other sheet, Im not done that yet. you’re on your own, sorry!
Ohh our labs for “Newton’s particle model for the refraction of light” was due today too, and we got to know our term marks. So for those who weren't here his period, you didn’t miss out on much.
