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.

WebJan 9, 2024 · The number of photoelectrons emitted per unit area per unit time is directly proportional to the intensity of light used. is a correct statement. The frequency of the light is proportional to the energy of the light (through E = h f) and therefore only affects the kinetic energy of the photoelectrons coming out from the surface not their numbers. http://electron6.phys.utk.edu/phys250/modules/module%201/photons.htm is the baryonyx a carnivore
