In a Young's double-slit experment, the fringe width is `beta`. If the entire arrangement is now placed inside a liquid of refractive index `mu`, the fringe width will become

A

`(beta)/(n+1)`

B

`nbeta`

C

`(beta)/(n)`

D

`(beta)/(n-1)`

Text Solution

Verified by Experts

The correct Answer is:
C
`beta = (lambdaD)/(d)` as `beta prop lambda` and `lambda prop (1)/(n)`
`beta.` .(in medium) `= (beta)/(n)`
