WebSep 12, 2024 · A photon’s energy depends only on its frequency f. Explicitly, the energy of a photon is Ef = hf where h is Planck’s constant. In the photoelectric effect, photons arrive at the metal surface and each photon gives away all of its energy to only one electron on the metal surface. WebSep 12, 2024 · According to the theory of special relativity, any particle in nature obeys the relativistic energy equation (6.4.1) E 2 = p 2 c 2 + m 0 2 c 4. This relation can also be applied to a photon. In Equation 6.4.1, E is the total energy of a particle, p is its linear momentum, and m 0 is its rest mass.
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), 29.12 where E is the energy of a single photon and c is the speed of light. When working with small systems, energy in eV is often useful. WebJan 30, 2024 · The energy of a photon is a discrete quantity determined by its frequency. This result can be determined experimentally by studying the photoelectric effect. The kinetic energy of an emitted electron varies …
