WebFeb 11, 2016 · The easiest way to measure the energy of a photon, is to make a reaction using the photoelectric effect. The photon hits a surface, knocks out an electron, and the electron can be prevented from carrying charge away from the surface by putting a small attracting voltage onto that surface (this is called the 'stopping potential'). WebPhoton is the quantum of light and light is electromagnetic wave which carries momentum and energy. i.e, If the total energy transferred to a surface in time t is U, then p=U/c . So …

This causes a change in the photon’s energy, and therefore in its wavelength (since E = h =hc/ ). Compton’s discovery of this effect
WebJan 30, 2024 · These packets of energy can be transmitted over vast distances with no decay in energy or speed. Photons travel at the speed of light, 2.997x10 8 m/s in empty space. The speed of a photon through space can be directly derived from the speed of an electric field through free space. Maxwell unveiled this proof in 1864.
WebA photon is a quantum of EM radiation. Its energy is given by E = hf and is related to the frequency f and wavelength λ of the radiation by. E = hf = hc λ (energy of a photon) E = h f = h c λ (energy of a photon), where E is the energy of a single photon and c is the speed of light.
