How to calculate the energy of a photon
WebShort answer: a photon is a particle of light. Longer answer: light is energy. Sometimes we think of light as being a wave in the form of an electro-magnetic wave but other times it can be described as a particle. A photon in this case, is 1 unit of light with a variable amount of energy which depends on its frequency. WebIn order to find the energy of the photon that was absorbed or emitted, you always take the higher energy level and subtract from it the lower energy level. So in this case, we would take -6eV, and subtract from it -10eV, which tells us that it would take a four eV photon to bump an electron up to that energy level, and the electron would emit a four eV photon …
