An AIR station is broadcasting the waves...

An AIR station is broadcasting the waves of wavelength `300 metres`. If the radiating power of the transmitter is `10 kW`, then the number of photons radiated per second is

A

`1.5 xx 10^(29)`

B

`1.5 xx 10^(31)`

C

`1.5 xx 10^(33)`

D

`1.5 xx 10^(35)`

Text Solution

Verified by Experts

`p=(W)/(t)=(nhc)/(lambdat)rArr((n)/t)=(plambda)/(hc)=(10xx10^(3)xx300)/(6.6xx10^(-34)xx3xx10^(8))`
`=1.5 xx 10^(31)`
