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. Web1 day ago · In a usual solar cell, the energy of a single photon is transferred to two free charges in the material, but no more than that. However, a few molecular materials like …

WebShort answer: a photon is a particle of light. Longer answer: light is energy. Sometimes we think of light as being a wave in the form of an electro-magnetic wave but other times it can be described as a particle. A photon in this case, is 1 unit of light with a variable amount of energy which depends on its frequency. 1 comment ( 24 votes) Upvote WebSep 9, 2024 · Photon Definition.
