X-rays of wavelength 3.550 Angstroms (10-10 m) incident on an aluminum target undergo Compton scattering. (a) For a photon scattered at 84º relative to the incident beam, what is the wavelength of the scattered photon? m (b) What are the magnitude of the momentum and the energy of this scattered photon at this angle? momentum kg. m/s energy
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...
