The photon model of light
WebbIn this theory, light consists of individual packets of energy called photons. A beam of light can then be thought of as many separate photons each carrying a specific amount of energy, rather than a continuous stream of energy. When a photon is absorbed it transfers all of its energy at once. WebbEach photon moves at the speed of light and carries an energy quantum E f. E f. A photon’s energy depends only on its frequency f. Explicitly, the energy of a photon is. ... Equation 6.14 in Einstein’s model tells us that the maximum kinetic energy of photoelectrons is a linear function of the frequency of incident radiation, ...

WebbThe term photon, which is now applied to the energy quantum of light, was later coined by the American chemist Gilbert N. Lewis. Einstein supported his photon hypothesis with … WebbNow we mentioned that the energy of each photon of light was also a basic property. It turns out that there is a simple relationship between the energy of a photon and the corresponding wavelength of that photon: E (photon) = (constant) / (wavelength).
