The energy of a photon can be calculated using the correlation between Energy (E), Frequency (ν), Wavelength (λ), and Planck’s Constant (h).
Creation and destruction of photons must conserve energy and momentum. The magnitude of the momentum of a photon is p = hf/c = h/λ. Problem: What is the energy of a photon of blue light (λ = 450 nm) and of a photon of red light (λ = 700 nm) in units of eV = 1.6*10-19 J? Solution: E = hc/λ.
