The photon energy is the energy carried by a single proton.
The equation used for calculating photon energy is:
E = hc / λ
where h = Planck constant
c = speed of light and
λ = wavelength of photon
frequency = f = c / λ
replace c /λ with f in the equation of photon energy
E = hf
frequency = 610 thz = 6.1 x 10¹⁴hz
h = 6.26 x 10⁻³⁴ js
E = 6.26 x 10⁻³⁴ x 6.1 x 10¹⁴
E = 3.8 x 10⁻¹⁹ j
