If c is the velocity of light in free space, the time taken by light to travel a distance x in a medium refractive index `mu` is

A

`(x)/(c)`

B

`(mux)/(c)`

C

`(x)/(muc)`

D

`(c)/(mux)`

Text Solution

Verified by Experts

The correct Answer is:
B
Velocity of light in a medium `v = c/mu`
We knows time taken `t = x/v`
`rArr r = (x)/(c//mu)`
`rArr t = (mux)/(c)`
