Transcript Chapter2: Compton Effect

Suppose that a beam of 0.2-MeV photon is
scattered by the electrons in a carbon
target. What is the wavelength of those
photon scattered through an angle of 90o?
A. 0.00620 nm
B. 0.00863 nm
C. 0.01106 nm
D. 0.00243 nm
E. Non of the above

 X-rays
of wavelength 0.2400 nm are
Compton scattered and the scattered
beam is observed at an angle of 60
degree relative to the incident beam.
 Find (a) the wave length of the
scattered x-rays, (b) the energy of the
scattered x-ray photons, (c) the kinetic
energy of the scattered electrons, and
(d) the direction of travel of the
scattered electrons

 (c)
A 0.0016-nm photon scatters from a free
electron. For what scattering angle of the
photon do the recoiling electron and the
scattered photon have the same kinetic
energy?

Which of the following statement(s) is (are) true?
I. Photoelectric effect arises due to the absorption
of electrons by photons
II.Compton effect arises due to the scattering of
photons by free electrons
III. In the photoelectric effect, only part of the
energy of the incident photon is lost in the process
IV.In the Compton effect, the photon completely
disappears and all of its energy is given to the
Compton electron
