Light passes through a glass slab of refractive index .n. and thickness .t.. If .C. is the speed of light in free space, then time taken to emerge | light out of glass slab will be ......

`(t)/(nc)`

ntc

`(nt)/(c)`

`(tc)/(n)`

Text Solution

Verified by Experts

The correct Answer is:

time=(distance)/(speed)=`t/c[becausen=c/v implies c=c/n`]
`therefore` Time `=(nt)/(c)`
