The frequency of a light wave in a material is `2xx10^(14)Hz` and wavelength is `5000 Å`. The refractive index of material will be

A

`1.33`

B

`1.40`

C

`1.50`

D

`3.00`

Text Solution

Verified by Experts

The correct Answer is:
D
Refractive index `mu=(c)/(v)=(c)/(v lambda)`
`=(3xx10^(8))/(2xx10^(14)xx5000xx10^(-10))=3`
