WebSuppose the incident photon has energy E0 = hf0 and momentum p0. It hits a stationary electron with rest energy mc2 and zero momentum. After the collision, the outgoing photon has energy E = hf and momentum p that makes an angle θ with p0. The electron recoils with energy E e and momentum p e. Conservation of energy and momentum gives us E …

Photon energy - Wikipedia

WebTo find the photon energy in electronvolts using the wavelength in micrometres, the equation is approximately This equation only holds if the wavelength is measured in micrometers. The photon energy at 1 μm wavelength, the wavelength of near infrared radiation, is approximately 1.2398 eV. 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. biological potash machine https://nicoleandcompanyonline.com
