Question

A microwave oven uses electromagnetic radiation at 2.4GHz. What is the energy of each microwave photon?
My answer is 9.9*10^-6 eV The next question is where I'm a little stumped. Pleasehelp!! At what rate does a 900-W oven produce photons? ________________ photons/s A microwave oven uses electromagnetic radiation at 2.4GHz. What is the energy of each microwave photon?

Explanation / Answer

Frequency   f = 2.4 * 10 ^ 9 Hz energy E = h f where h = planck's constant = 6.625 * 10 ^-34 J s from this E = 15.9 * 10 ^ -25 J Power P = 900 W energy per second   E ' = 900 J So, rate of photons produced = E ' / E                                              = 56.603 * 10 ^ 25 photons / s
