The frequency of a light ray is `6 xx 10^(14)` Hz. If frequency when it propagates in a medium of refractive index 1.5 will be

A

`6 xx 10^(14)` Hz

B

`4 xx 10^(14)` Hz

C

`9 xx 10^(14)` Hz

D

`1.67 xx 10^(14)` Hz

Verified by Experts

The correct Answer is:

A

Frequency of a wave remains unchanged when it propagates from one medium to other medium.
`therefore" "v. = v = 6 xx 10^(14)` Hz
