What term describes the energy carried by a single electromagnetic wave?

Explanation:
Energy describes the amount of energy transported by that electromagnetic wave. A wave can transfer energy from the source to a receiver, but “power” would be the rate at which energy is transferred (energy per unit time). The wavelength is the spatial distance between repeating features of the wave, and the frequency is how many oscillations occur each second; neither of these alone tells you how much energy is carried. For a single pulse or wave, the total energy depends on the wave’s amplitude and duration (or, in quantum terms, the number of photons times h f). So the best term for what a single wave carries is energy.
