  What is the energy of one photon radiation? (Probably super basic for you)

+ 0 like - 1 dislike

So, this is given question:
The radio station emits radiation power of 6 kW, wavelength 3 m.
a) What is the energy of one photon radiation?
b) How many photons are emitted in 5s?

Just to don't get confused, photons are the same as quinces (because I got confused there, teacher didn't told us that lol). Probably super-simple task, but I can't solve this.

I tried this:


But here I came across problems, I know that h is const., but don't know what is going to be with c and f...
