Find the number of photons emitted per second. Please
-
The energy, E, contained within a photon is given by:
E = hf = hc/λ
where h is Planck's constant [1.626 * 10^-34 J.s]
f is the frequency in Hz
c is the velocity of light [3.00 * 10^8 m/s]
λ is the wavelength in metres
In this case:
E = 1.626 * 10^-34 * 3* 10^8 / 0.122
E = 3.998 * 10^-25 J
Power = [energy] / [time]
So in 1 s the oven will output 760 J of energy
Number of photons = [output energy] / [energy per photon]
Number of photons = 760 / (3.998 * 10^-25) = 1.90 * 10^27
E = hf = hc/λ

Number of photons = [output energy] / [energy per photon]
Number of photons = 760 / (3.998 * 10^-25) = 1.90 * 10^27
