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 9.00 × 10-12m. Find the x and y components of the momentum of the scattered electron.
