The optical path of a monochromatic ligh...

The optical path of a monochromatic light is same if it goes through 4.0 cm of glass or 4.5 cm of water. If the refractive index of glass is 1.53, the refractive index of the water is

A

`1.30`

B

`1.36`

C

`1.42`

D

`1.46`

Text Solution

Verified by Experts

As optical paths are equal, hence
`n_(g)x_(g)=n_(w)x_(w)`
`n_(w)=n_(g)(x_(g))/(x_(w))`
Refractive index of the water, `n_(w)=1.53xx(4.0)/(4.5)=1.36`
