Question

A beam of 0.68-nm photons undergoes compton scattering from free electrons. what are the energy and momentum of the photons that emerge at a 45° angle with respect to the incident beam​

Answer 1

What is the kinetic energy of the electron after the photon is scattered?

Since thethe kinetic energy is supplied by a part of the energy of the incident photon,hence gain in electron energy is equal to the loss in photon energy. So the kinetic energy of the recoil electron is obtained by simply subtracting the energy of the scattered photon from the energy of incident photon

Answer 2

Answer:

Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. ... Familiar examples of oscillation include a swinging pendulum and alternating current.
