A radio transmitter works at a frequency of 880 KHz and a power of 10 KW. The no. of photons emitted per second are :

A

`1.72xx10^(31)`

B

`1327xx10^(34)`

C

`13.27xx10^(34)`

D

`0.075xx10^(-34)`

Text Solution

Verified by Experts

The correct Answer is:
A
No. of photons/s =`(P)/(E)=(P)/(hv)`
`=(10xx10^(3))/(6*6xx10^(-34)xx88xx10^(4))=1*72xx10^(31)`
