How can we calculate the energy of light?
IF we consider it as a wave then energy is 1/2εE^2 or rather it is the energy density
IF we multiply it by small volume dV we get energy in that volume as 1/2εE^2 dV
But if we consider as a particle its energy is hf. Let's say there are n photons in volume dV
So energy will be nhf
So both the energies will be different or same? Should be same but i don't know - I'm still a beginner in quantum physics-related studies
