WebApr 12, 2024 · Delta-c Mechanics is an alternate approach to the physical interaction between mass and photons by way of the Feynman action path probabilities, offering a new approach to mechanical dynamics, and ... WebMar 6, 2024 · Photons of higher-frequency violet light have more energy than photons of lower-frequency red light, so they're more likely to knock electrons out (and liberate them with higher energy). The photons need a minimum threshold frequency (a minimum amount of energy) to free electrons and produce a photoelectric effect, known as the work function.

WebMar 26, 2024 · Now because the energy of the photon is same as that of the energy of the transition energy, the electron in the ground state will move to the next higher energy level. This is known as absorption. But because the total energy of the atom is higher it would want to go to a lower energy level. This is known as spontaneous emission. 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 …

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. When working with small systems, energy in eV is often useful.
