X-rays with wavelengths of 0.2599 nm are detected at a scattering angle of = 132° in a Compton-scattering experiment, as shown in the drawing. Find (a) the wavelength of an incident photon, (b) the energy of an incident photon (in eV), (c) the energy of a scattered photon (in eV), and (d) the kinetic energy of the recoil electron (in eV). (For accuracy, use h = 6.626 x 10-34 J·s and c = 2.998 x 108 m/s.)
