A photon of wavelength 5.58 pm scatters at an angle of 122° from
an initially stationary, unbound electron. What is the de Broglie
wavelength(in pm) of the electron after the photon has been
scattered??
Notice: Answer is not (9.29, 2.12, 2.06, nor 4.11)pm
Explanation:
The de Broglie wavelength of a massive particle is related to
its momentum in the same way that a photon's momentum is related to
its wavelength.
The well-known Compton scattering relationship gives the final
wavelength of...
