What is the momentum of a photon having frequency `1.5 xx 10^(13) Hz` ?

A

`3.3 xx10^(-29) kgm//s`

B

`3.3 xx10^(-34) kgm//s`

C

`6.6 xx10^(-34) kgm//s`

D

`6.6 xx10^(-30) kgm//s`

Text Solution

Verified by Experts

The correct Answer is:
A
`P=(hv)/c=(6.6xx10^(-34)xx1.5xx10^(13))/(3xx10^8)=3.3 xx10^(-29)kgm//s`
