How much energy per photon is there in a wavelength of 60 micrometers?
How much energy per photon is there in a wavelength of 60 micrometers?
I got 3.31 X 10 ^-21 J / photon
How much energy for one mole of those photons?
wavelength = speed of light/frequency
frequency = c/wavelength = 3E8/60E-6 = 5E12 Hz
energy = hf = 6.626E-34 Js * 5E12 Hz = 3.31E-21 J/photon
one mole of photons = 6.02E23 photons
energy of one mole of photons = 6.02E23*3.31E-21 = 1990 J
