In Young's double slit experiment, the sepcaration between the slits is halved and the distance between the slits and the screen is doubled. The fringe width is

A

(a) Will not change

B

(b) Will become half

C

(c) Will be doubled

D

(d) Will become four times

Text Solution

Verified by Experts

The correct Answer is:
D
`beta=(lambdaD)/(d)implies` If D becomes twice and d becomes half so `beta` becomes four times.
