Question

Each of the statments below may or may not be true. Enter the letters corresponding to all the true statements. (Give ALL correct answers, i.e., B, AC, BCD...)

In the two-slit experiment, y1, the distance from the central maximum from the first bright spot ...

     A) doesn't depend on the slit separation.
     B) is smaller than the wavelength of the light.
     C) decreases if the screen is moved away from the slits.
     D) is larger for red light than for yellow light.
     E) decreases if the frequency of the light increases.

Explanation / Answer

DE

we know the formula for y1 = lamda*R/d (here lamda is wavelength, R is distance from slts to screen, d is slit separtion)

and wave speed, c = lamda*f

when f increases, lamda decreases
