A light wave has a frequency of `4xx10^(14)Hz` and a wavelength of `5xx10^(-7)` meters in a medium. The refractive index of the medium is

A

1.5

B

1.33

C

1.25

D

1.75

Text Solution

Verified by Experts

Refractive index of the medium,
`mu=(c)/(v)=(c)/(nlambda)=(3xx10^(8))/(4xx10^(14)xx5xx10^(-7))=15`
