First of all, we can calculate the frequency of the photon, which is related to the wavelength by the following equation:
where c is the speed of light and
is the photon wavelength. Substituting into the formula, we find the frequency
Now we can find the energy of the photon with the following equation:
where h is the Planck constant. Substituting numbers, we find
where c is the speed of light and
Now we can find the energy of the photon with the following equation:
