A helium-neon laser emits light of wavelength 632.8 nm and has a
power output of 2.0 mW. How many photons are emitted per second by
this laser?
________ photons/s
Homework Answers
E in photon = hc/lambda = (6.62E-34) * (3E8) / 632.8E-9 =
3.13843E-19 J
Photons per second = Total Power / E_photon = 3E-3 / 3.13843E-19 =
9.55892E+15 photons/second
Energy of a photon at 632.8 nm is
E_photon = hc/lambda = (6.62E-34) * (3E8) / 632.8E-9 = 3.13843E-19
J
Photons per second = Total Power / E_photon = 2E-3 / 3.13843E-19 =
6.37261E+15 photons/second
