Finding photon energy from wavelength
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.
