What is the frequency of photon, whose momentum is `1.1xx10^(-23) kg ms^(-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
`because E=mc^2, E=hv`
`therefore mc^2 =hv`
`v=(mc^2)/(h)=(1.1xx10^(-23)xx3xx10^8)/(6.6xx10^(-34))=5xx10^18` Hz
