Question
20 keV electron is brought to rest by colliding twice with
target nuclei . (Assume the nuclei remain stationary.)
The wavelength associated with the photon emitted in the second
collision is 130 pm greater than that associated with the photon
emitted in the first collision. (a) What is the kinetic energy of the
electron after the first collision? What are (b) the wavelength l1
and (c) the energy E1 associated with the first photon? What are (d)
l2 and (e) E2 associated with the second photon?
