A ray of light passes through a glass plate of thickness and refractive index`mu` if the speed of light in vacuum is `c`,then the time taken by light in passing through the plate will be-

A

`mut`

B

`(mut)/(c)`

C

`(tc)/(c )`

D

`t/(mu c)`

Text Solution

Verified by Experts

The correct Answer is:
2
time=`("distance")/("velocity")=("optical path")/(velocity of light")`
` t^(')=(mut)/(c )`
