Photon - Wikipedia
WEBA 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.
Wave–particle duality - Wikipedia
WEBA photon of wavelength comes in from the left, collides with a target at rest, and a new photon of wavelength ′ emerges at an angle . The target recoils, and the photons have provided momentum to the target.
DOE Explains...Photons | Department of Energy
WEBPhotons travel in a wave-like fashion, in which the local electric and magnetic field oscillates in intensity, regularly swinging back and forth between high and low energy levels. The energy in the photons determines the type of …
What is the relation between electromagnetic wave and photon?
WEBDec 18, 2014 · Hence, light is an electromagnetic wave. Light consists of photons; and thus each photon carries a unit of energy. This behavior is demonstrated by the photoelectric and Compton effects. Since light is an electromagnetic energy, photons must also carry electromagnetic field and a unit of it.
