A photon undergoes Compton scattering off a stationary free electron.
The photon scatters at from its initial direction;
its initial wavelength is . What is the electron鈥檚 kinetic energy?
Show that , the fractional loss of energy of a photon during a collision with a particle of mass m, is given by
where E is the energy of the incident photon, is the frequency of the scattered photon, and is defined as in Fig. 38-5.
Light strikes a sodium surface, causing photoelectric emission. The stopping potential for the ejected electrons is 50 V, and the work function of sodium is 2.2 eV. What is the wavelength of the incident light?
Question: Show that Eq. is indeed a solution of Eq. by substituting and its second derivative into Eq. and noting
