The momentum of a photon of an electromagnetic radiation is `3.3xx10^(-29)` kg m/s. The frequcncy of the associated wave is `(h=6.6xx10^(-34)Js,c=3xx10^(8)m//s)`

A

`3.0xx10^(3)Hz`

B

`6.0xx10^(3)Hz`

C

`7.5xx10^(12)Hz`

D

`1.5xx10^(13)Hz`.

Text Solution

Verified by Experts

The correct Answer is:
D
We know that moment `p=mv=(h)/(lambda)`
`hv=(hc)/(lambda)pc, v=(pc)/(h)=(3.3xx10^(-29)xx3xx10^(8))/(6.6xx10^(-34))`
`=1.5xx10^(13)Hz`.
