How many photon/sec??

An FM radio transmitter has a power output of 100 kW and operates at a frequency of 97.5 MHz. How many photons per second does the transmitter emit?

We will help you with your homework but we won't do your homework. :wink:
 


Ok, consider first that the power output of the transmitter is the energy released from the transmitter in a given time (in the form of photons) divided by that time, as in

P_{ower of transmitter}=\frac{E_{nergy emitted}}{t_{ime}} and think of the energy as a number of photons. Where do you get?
