Consider the diffraction pattern for a small pinhole. As the size of the hole is increased

A

the size decrease

B

the intensity increase

C

the size increase

D

the intensity decrease

Text Solution

Verified by Experts

The correct Answer is:
A, B
(a,b) (a) When a decrease w increases.
So, size decreases.
(b) Now, light energy is distributed over a small are and intensity `prop(1)/("area")` as area is decreasing so intensity increases.
