How to calculate energy of light emitted
WebThe energy ( e) of a photon is given by the equation e = hc /λ, where c is the velocity of light, h is Planck’s constant, and λ is the light wavelength. The energy ( E) of an einstein is E = Ne = Nhc /λ = 28,600/λ, when E is in kilocalories and λ is given in nanometres (nm; 1 nm = 10 −9 metres).
