what exactly is the energy of the wave? how to think about it generally, in electromagnetic waves and in relation to amplitude? I can think about the kinetic or potential energy that a particle can get from that kind of wave or the sum of all such energy in all particles under wave's influence but I am not sure what's the intuition behind this term. also how can we derieve its proportion to the amplitude of the wave?
