Revealing the dynamic mechanism behind photoelectric effect

Mechanism-Revealed Physics (13/40) ----- by Bingcheng Zhao

Revealing the dynamic mechanism behind photoelectric effect. Photoelectric effect is one of the well-known phenomena in physics. However, the dynamic mechanism behind photoelectric effect ---- what force causes photoelectric effect to occur, i.e., the dynamic principle of why and how an electron being ejected immediately after it absorbs a high-frequency photon whereas not be ejected after absorbing a low-frequency photon, has not been and cannot be revealed until the discovery of OEPIEP law*. (*Note, OEPIEP law = the law of orbiting electron periodic impulse emitting photons, P. 193 ~ 214, Ch.2A, reference #1). The dynamic mechanism behind photoelectric effect is revealed with the dynamics of OEPIEP law as following (P. 227 ~ 229, 2.9.1, Ch.2B, reference #1).

Immediately after an orbiting electron absorbs a high-frequency photon (e.g., a photon of ultraviolet light), the moving velocity of the electron increases quickly and suddenly, causing the increase of electron-self-exerting magnetic force (Fm) so quickly and suddenly that its magnitude instantly exceeds that of Coulomb force (Fe) [i.e., Fm > Fe in magnitude], resulting in the electron being ejected immediately — almost without a time delay with respect to the moment at which the electron absorbs the photon [Fig. 2.7 (a), P. 228 (reference #1)]. On the contrary, immediately after an orbiting electron absorbs a low-frequency photon (e.g., a photon of red or infrared light), while the moving velocity of the electron can also increase significantly, the increase is not rapidly and strongly enough to reach the extent that the magnitude of electron-self-exerting magnetic force (Fm) instantly exceeds that of Coulomb force (Fe) [i.e., still the value of Fe > Fm]. As a result, controlled by the action of Fe, the orbit of the electron decreases correspondingly [Fig. 2.7 (b)], i.e., the electron does not leave off atom, photoelectric effect thereby does not occur. {*Note, the detailed information about electron-self-exerting magnetic force (Fm) is in 2.3 and 2.4, Ch.2A (P. 196 ~ 203, reference #1)}.
