An X-ray photon is scattered at an angle of = 180.0° from an electron that is initially at rest. After scattering, the electron has a speed of 5.40 x 106 m/s. Find the wavelength of the incident X-ray photon.
What is the maximum amount by which the wavelength of an incident photon could change when it undergoes Compton scattering from an atom or molecule with a 60.0 u mass? (1 u = 1.66 x 10-27 kg).
In a Compton scattering experiment, the incident X-rays have a wavelength of 0.2682 nm, and the scattered X-rays have a wavelength of 0.2706 nm. Through what angle in the drawing are the X-rays scattered?
