X-rays with wavelengths of 02597 nm are detected at a

Question

X-rays with wavelengths of 0.2597 nm are detected at a scattering angle of = 170° in a Compton-scattering experiment. 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.)
