1. PHY240 Question #6
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 nm
B nm
C nm
D nm
E. Non of the above

2. PHY240 Question #7
X-rays of wavelength 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

3. PHY240 Question #8
(c) A 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?

4. PHY240 Question #9 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
