PH 122 Chapter Notes - Chapter 38: Compton Scattering, Compton Wavelength, Electric Field
Document Summary
The energy of a photon is expressed as. The electrons ejected from a photoelectric effect are referred to as: the collection of photoelectrons as a flow creates a photoelectric photoelectrons. current. ) is the point in potential difference at which the photoelectric current reaches zero: a photoelectric effect will not occur, regardless of the intensity of the incident. If the energy of the absorbed photon is equal to the work function, the electrons barely escape but have no kinetic energy the frequency is at the cutoff frequency. electrons. If the energy of the absorbed photon is less than the work function, the electrons cannot escape. 38-3 photons, momentum, compton scattering, light interference: photons have momentum related by energy, frequency and wavelength expressed as: In compton scattering, x-ray beams scatter as particles (as photons) from loosely bound electrons in a target. The x-ray photons lose energy and momentum to the target electron.
