A laser emit monochromatic light of `6.0xx10^(14)Hz` frequency and produce power of `2xx10^(-3)` W.No of photon produced per second will be…..

A

`5xx10^(16)`

B

`5xx10^(17)`

C

`5xx10^(14)`

D

`5xx10^(15)`

Text Solution

Verified by Experts

The correct Answer is:
D
Power P=nhf
`impliesn=(P)/(hf)=(2xx10^(-3))/(6.6xx10^(-34)xx6xx10^(14))=5xx10^(15)`
