The maximum change in wavelength during Compton scattering occurs when   a the photon scatters at an angle of 90°. b the electron scatters at an angle of 90°. c the photon scatters at an angle of 180°. d the electron scatters at an angle of 180°.

A typical red laser pointer has a power output of 1.50 mW and a wavelength of 680 nm. Find how many photons per second the laser emits in units of 10¹5 photons/sec. (A) 2.31 (B) 5.13 (C) 4.97 (D) 7.49 (E) 3.78

You use 0.124 nm x-ray photons in a Compton-scattering experiment. At what angle is the wavelength of the scattered x rays 1.0% longer than that of the incident x rays? 70.6° 67.0° 60.7° 56.5°

X-ray photons of wavelength 0.0248 nm are incident on a target and the Compton-scattered photons are observed at 80.0° above the photons' incident line of travel. [Use relativistic units for this problem!] (a) What is the wavelength of the scattered photons?  nm (b) What is the momentum of the incident photons? eV/c What is the momentum of the scattered photons? eV/c (c) What is the kinetic energy of the scattered electrons? eV (d) What is the momentum (magnitude and angle) of the scattered electrons? eV/c
