The frequency of a wave of light is `12xx10^14 s^(-1)` . The wave number associated with this light is

A

`5xx10^(-7) m`

B

`4xx10^(-8) cm^(-1)`

C

`2xx10^(-7) m^(-1)`

D

`4xx10^(4) cm^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
Frequency `v=12xx10^14 s^(-1)` and velocity of light `c=3xx10^10 cm s^(-1)` . We know that the wave number `barv=v/c =(12xx10^14)/(3xx10^10)=4xx10^4 cm^(-1)`
