Show that the laws of momentum and energy conservation forbid
the complete absorption of a
photon by a free electron. (Note: This is NOT the photoelectric
effect. In the photoelectric effect, the
electron is not free; the metal participates in momentum and energy
conservation.

In the Compton effect, momentum conservation applies, so the total momentum of the photon and the electron is the same before and after the scattering occurs. Suppose that in Figure 29.10 the incident photon moves in the +x direction and the scattered photon emerges at an angle of θ = 90.0°, which is in the -y direction. The incident photon has a wavelength of 8 × 10-12 m. Find the x and y components of the momentum of the scattered...

This question has multiple parts. Work all the parts to get the most points. The energy of a photon needed to cause ejection of an electron from a photoemissive metal is expressed as the sum of the binding energy of the electron plus the kinetic energy of the emitted electron. When photons of 4.40x107m light strike a calcium metal surface, electrons are ejected with a kinetic energy of 1.75x10-20 J. a Calculate the binding energy of the calcium electrons. b...
