The velocity of light in glass whose refractive index w.r.t, air is ` 1.5 ` is ` 2 xx 10^(8) m//s `. In a certain liquid, the velocity of light is found to be ` 2.5 xx 10^(8) m//s `. The refractive index of the liquid w.r.t. air is

A

`0.64`

B

`1.20`

C

`0.80`

D

`1.44`

Text Solution

Verified by Experts

The correct Answer is:
B
`C = n_(L) xx v_(L) = n_(g) xx v_(g) (because n = (C)/(v))`
`therefore n _(L) xx 2.5 xx 10^(8) =1 .5 xx 2 xx 10^(8)`
`therefore n_(L) = (1.5 xx 2 xx 10^(8))/(2.5 xx 10^(8)) = (6)/(5) = 1.2`
