Asked by Kez

microwave ovens work by irradiating food with microwaves, which is absorbed by the water molecules in the food and is converted into heat. Assuming that microwave ovens emit radiation with a wavelength of 12.2cm, calculate how many photons are emitted per second in a 1000-Watt microwave oven.
Answered by DrBob222
1000 watts = 1000 joules/second

E = hc/wavelength
E = 6.626E-34*3E8/12.2E-2 for one photon.
1.6E-24 J/photon x # photons = 1000 joules/sec.
Solve for # photons.

1000/(1.6*10^-24) =
6.25*10^26 photons/sec
