Question

REMARKS It is also possible to find this answer by substituting into the energy expressior stage, but the algebraic derivation is more elegant and instructive because it shows how cha energy are related to changes in wavelength. QUESTION The incident photon loses energy. Where does it go? (Select all that apply.) It goes into the emission of additional photons. It is transformed into photon momentum It goes into kinetic energy of the electron It becomes heat Energy conservation does not apply Consider that the electron was regarded as being initially at rest and is moving after the colli its energy changed, and what caused it to change? Note that energy and momentum conser apply, and that energy and momentum are physically distinct.

Explanation / Answer

The inelastic scattering of a photon by an electron results in a decrease in energy (increase in wavelength) of the photon (which may be an X-ray or gamma ray photon), called the Compton effect. Part of the energy of the photon is transferred to the recoiling electron. The transfer of momentum causes this change in energy.
