How to calculate number of photons from energy and wavelength?

Answered by admin @ 06/08/2021

Answer:

According to the equation E=n⋅h⋅ν (energy = number of photons times Planck's constant times the frequency), if you divide the energy by Planck's constant, you should get photons per second. Eh=n⋅ν → the term n⋅ν should have units of photons/second.
