You shine monochromatic light of
wavelength through a narrow slit of
width b≈λb≈λ and onto a screen that is very far away from
the slit. What do you observe on the screen?
What does it mean for two light waves to be in
phase ?
You shine monochromatic light of wavelength through a
narrow slit of width and onto a screen that is very far
away from the slit. What do you observe on the screen?
Monochromatic light is directed through two narrow parallel
slits. There is a viewing screen away from the
slits that is used to observe the interference pattern. If you
submerged the entire apparatus in water, how is the new
interference pattern different from the original one?
Light propagating in a material 1 with index of
refraction is incident on a new material 2 with index of
refraction . Some of the incident light reflects at this
boundary between materials 1 and 2 and continues to propagate in
material 1. How does the phase of the reflected light compare to
the phase of the incident light?

Problem 3 (15 points Select one correct answer from the available options in the below parts a) 13 points: You shine monochromatic light of wavelength / through a narrow slit of width band onto a screen that is very far away from the slit. What do you observe on the screen? OA series of bright and dark fringes that are of equal widtbs OA series of bright and dark fringes with the central bright ringe being wider and brighter than the other bricht fringes Two brighttringes and three dark fringes COne bright and b) [3 points] What does it mean for two light waves to be in phase ? The two waves propagate in the same direction The two waves reach their maximum value at the same time and their minimum value at the same time The two waves have the same wavelength and Irequency The two waves have the same amplitude c) la points) You shine monochromatic light of wavelength through a narrow slit of width band onto a screen that is very far away from the slit. What do you observe on the screen? CT'wo hright fringes and three dark fringes DA series of bright and dark fringes that are of equal widths OA series of bright and dark fringes with the central hright fringe being wider and brighter than the other bright fringes One bright bard d) (3 points Monochromatic light is directed through two Darrow parallel slits. There is a viewing screen away from the slits that is used to observe the interference pattern. If you submerged the entire apparatus in water, how is the new interference pattern different from the original one? The pattern does not change The bright and dark fringes are closer together The bright and dark fringes are farther apart e) la points) Light propagating in a material 1 with index of refractiva , is incident on a new material 2 with index of refraction N, < Souse of the incident light reflects at this boundary between materials 1 and 2 and continues to propagate in material 1. How does the phase of the reflected light compare to the phase of the incident light? The reflected lig in with the incident light The reflected light is one-half cycle aut af phase with the incident light There is no reflected light because Light will not reflect of a material with a lower index of refraction than the initial material The reflected light is one-quarter out of phase with the incident light
