You need to know the photon's frequency or wavelength.

If you know the wavelength, divide the speed of light by the photon's wavelength

to find the frequency.

Once you have the photon's frequency, multiply that by Planck's Konstant.

The product is the photon's energy.

The energy of a photon can be calculated using the formula E=hf, where E is energy, h is Planck's constant (6.63 x 10^-34 J.s), and f is the frequency of the photon. Alternatively, you can use the formula E=hc/λ, where c is the speed of light (3.00 x 10^8 m/s) and λ is the wavelength of the photon.
