A 84 kW AM radio station broadcasts at 1000 KHz.How many photons are emitted each second by the transmitting antenna?

Question

Quizplus · Accepted Answer

The energy of a single photon is given by E = hf, where h is Planck's constant and f is the frequency. The power of the radio station is given by P = N * E, where N is the number of photons emitted per second. Substituting the given values, we get:84 kW = N * (6.626 x 10^-34 J s) * (1000 kHz * 10^3 Hz/kHz)N = 1.3 x 10^32 photons/s
