Due on Monday, Nov 5 at 11:59 pm (EST) Optics 2: The light emitted by a laser is 1. A incoherent, B monochromatic and coherent. C invisible. D radioactive. Due on Monday, Nov 5 at 11:59 pm (EST) Optics 2: A diffraction grating has a spacing of 240 lines per mm and sits L = 11.4 cm from a screen. If the distance to the m = 5 maximum is x = 82.1 mm then what is the wavelength of the laser? Due on Monday, Nov 5 at 11:59 pm (EST) Optics 2: A double slit has a spacing of s = 0.1 mm and is illuminated with a laser which has a wavelength of = 644 mn. If the distance to the m = 4 maximum is y.4 = 28,3 mm then what is the distance to the screen? 3. A L = 0.910 m B L = 4.39 m C L = 17.6 m D L = 1.10 m Due on Monday, Nov Sat 11:59 pm (EST)]Optics 2: What is the process that allows the human eye to focus on objects at varying distances from the lens? 4. A Accommodation B inversion C Magnification D Ablation Due on Monday, Nov 5 at 11:59 pm (EST) Optics 2: A student plucks a hair from her head and places it in front of a laser with a wavelength of = 592 nm. The diffraction pattern is projected on a screen placed L = 1.4 m away. If the distance to the m = 4 minima is x4 = 15.8 mm, what is the thickness of her hair? 5. A W = 52.5 pm B w = 150 pm C w = 210 pm D w = 37.5 pm

Explanation / Answer

1. option B ---- monochromatic and cohenent
--------------------------------------------------

2. apply Y = mLR/d

L = Yd./mR

L = 0.0821* (1/240 mm)/5*0.114

L = 539 nm

option A it is
---------------------------------------
3. R = Yd/mL

R = 1.1 m

option D
--------------------------------------
4. magnification

option C

--------------------------------------------

5. Y = 4* 592 nm * 1.4/(d)

d =   210 um

option C
