What is the frequency of photon, whose momentum is `1.1xx10^(-23)kgms^(-2)`

A

`5xx10^(16)Hz`

B

`5xx10^(17)Hz`

C

`0.5xx10^(18)Hz`

D

`5xx10^(18)Hz`

Text Solution

Verified by Experts

The correct Answer is:
D
`becauseE=mc^(2)andE=hv`
`thereforemc^(2)=hv`
`rArrv=(mc^(2))/h=(mcxxc)/h=(pxxc)/h`
`rArrv=(1.1xx10^(-23)xx3xx10^(8))/(6.6xx10^(-34))=5xx10^(18)Hz`.
