In Young's double-slit experment, the frist maxima is observed at a fixed point P on the screen. Now, the screen is continously moved away from the plane of slits. The ratio of intensity at point P to the intensity at point O (center of the screen)

A

remians constant

B

keeps on decreasign

C

first decrease and then increases

D

first decreases and then becomes constant

Text Solution

Verified by Experts

The correct Answer is:
C
initially phase difference is `2pi` with increasing distance of screen phase differnce decreases to`pi` and than to zero.
