WebIn Einstein’s approach, a beam of monochromatic light of frequency f is made of photons. A photon is a particle of light. Each photon moves at the speed of light and carries an energy quantum E f. A photon’s energy depends only on its frequency f. Explicitly, the energy of a photon is E f = h f 6.13 where h is Planck’s constant. WebSep 12, 2024 · One peak is located at the wavelength \(λ\), which is the wavelength of the incident beam. The other peak is located at some other wavelength, \(λ'\). The two peaks are separated by \(Δλ\), which depends on the scattering angle \(θ\) of the outgoing beam (in the direction of observation). The separation \(Δλ\) is called the Compton shift.
