Photon energy is the energy carried by a single photon with a certain wavelength and frequency. These terms are related by an equation.

E = hv

where h is the Planck's constant (6.626 x 10-34 J s), v is the frequency.

We calculate the energy as follows:

E = hv

E = 6.626 x 10-34 J s (7.31 * 10^14 / s) = 4.84 x 10^-19 J
