Question

Part ID Answer the following problems True or False, and mark the scantron, A for true and B for false. 1) True/False, speed of light wave decreases in transparent media. 2) True/False, The frequency of a wave increases in a dense media. 3) True/False, the slit size of interference pattern is always greater than the wave length 4) True/False, When the distance from the slit to the screen, L increases, the fringe s ation y= decreases 5) True/False, If the wave traveling from less dense media to a denser media, the reflected wave will have phase change. (case ni

Explanation / Answer

1. (A) True as the light enters a transparent medium the speed of light is decreased in proportion to refractive index of the medium.

2. (B). false the frequency does not depend upon the medium

3. (A) the slit size is always greater than wavelength because if the wavelength is larger then the interference wont take place.

4. (B) false as the slit screen distance is directly proportional to the fringe seperation
