AGAIN?!

Man, looks like I'm doing this thing again.

Well today, we read the pages 2 - 7. This was about different theories like wave theory, tactile theory, emisson theory and corpuscular (particle) theory. After we read about this stuff, (yeah read) we did a work sheet on who made the theory, when the theory was made and what the theory was about, on top of that we had to draw a picture of each theory.

TACTILE THEORY
-Created by Plato
-Created during early Greece
-Stated that light consisted of "streamers" or filaments that was emitted from the eye and when that light hit an object, you were able to see it

EMISSION THEORY
-Created by the Pythagoreans
-Created in early Greece
-Stated that objects sent out light beams and the light would richocet off objects and would enter the eye, thus making it visible

PARTICLE THEORY
-Created by Newton
-Created in the 17th century
-States that light consisted of particles that traveled in straight lines

WAVE THEORY
-Created by Empedocles
-Created in early Greece
-States that light travels in waves

LOL! EYE see U. Yeah, sorry, I'm bored.

I'm choosing the scribe totally NOT random. I choose jaaaayp for my revenge, muahhahahha.... ahem... that is all.

Mid-Night Physics....

Yeah, well today... err, I mean yesterday we went over the answers of the lesson 15 vocabulary thingy. Answers below:

1) Amplitude
2) Frequency
3) Interference
4) Wavelength
5) Standing Wave
6) Sound Level
7) Opening-Pipe Resonator
8) Octave
9) Resonance
10) Consonance
11) Loudness
12) Dissonance
13) Timbre
14) Doppler Shift
15) Closed-End Pipe Resonator
16) Fundamental
17) Beat
18) Pitch
19) Harmonics
20) Echoes
21) Decibels

Well, when we finished this we went onto an experiment. We tested the sounds a closed pipe resonator with a tuning fork. To see what sounds it would make when we shifted it up and down a tube full of water. We were testing in which area where you would be able to hear the air compressing and rarefacting. We had 2 kinds of experiments: one of them in cold water and the other in hot water and in all the labs we do theres a lab work sheet that we had to do.

Oh yeah, we read pages 6 - 9 or something like that in the yellow book. The book talks about standing wave patterns in longitudinal waves. I shows where the antinodes and nodes are. We also read about Standing Waves with an open-tube resonator and standing waves with a closed-tube resonator.

Well thats the end of my post the next scribe was total random (not really since i just picked the first one) jeamille. Good luck with that.
