Photoelectric effect & wave-particle duality

Konichiwa!!!
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

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...
