Frequency of photon having 100 eV energy...

Frequency of photon having 100 eV energy is ……Hz [`h=6.62xx10^(-34)Js,1eV=1.6xx10^(-19)Js]`

A

`2.417xx10^(-16)`

B

`2.417xx10^(16)`

C

`2.417xx10^(17)`

D

`1.054xx10^(17)`

Text Solution

Verified by Experts

The correct Answer is:
B
E=hf
`therefore f=(E )/(h)=(100xx1.6xx10^(-19))/(6.62xx10^(-34))`
`=24169xx10^(17)`
`~~2.417xx10^(16)`Hz
