WebApr 1, 2024 · Figure 1.3.1 : The photoelectric effect involves irradiating a metal surface with photons of sufficiently high energy to cause the electrons to be ejected from the metal. (CC BY-SA-NC; anonymous) The classical picture underlying the photoelectron effect was that the atoms in the metal contained electrons, that were shaken and caused to vibrate ... WebFirst you cannot treat the energy of a classical light wave the same way as the energy of a photon. The energy of a photon is E = hf. The energy of a light wave is proportional to the square of the amplitude of oscillation of …

A photon (from Ancient Greek φῶς, φωτός (phôs, phōtós) 'light') is an elementary particle that is a quantum of the electromagnetic field, including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force. Photons are massless, so they always move at the speed of light in vacuum, 299792458 m/s (or about 186,282 mi/s). The photon belongs to the c… WebFeb 17, 2024 · photon, also called light quantum, minute energy packet of electromagnetic radiation.
