Question

When you look at a single slit diffraction pattern produced on a screen by light of a single wavelength, you see a bright central maximum and a number of maxima on either side, their intensity decreasing with distance from the central maximum. If the frequency of the light is increased,

A the pattern shrinks in size. (central maximum less wide; other maxima in closer to it)

B it does not affect the size of the pattern.

C the width of the central maximum increases, but the other maxima do not change in position or width.

D the width of the central maximum decreases, but the other maxima do not change in position or width.

E the pattern increases in size. (central maximum wider; other maxima farther from it)

Answer 1

Solution:

Where = c/f

So,

y = mcD/fa

y 1/f

If frequency is increased The wave length will decrease

The distance of separation decreases.

Ans: A A the pattern shrinks in size. (central maximum less wide; other maxima in closer to it)

I hope you understood the problem and got your answers, If yes rate me!! or else comment for a better solutions.
