Question:

A photon with wavelength 0.1100nm collides with a free electron that is initially at rest. After the collision the wavelength is 0.1132 nm.
(a) What is the kinetic energy of the electron after the collision? What is its speed?
(b) If the electron is suddenly stopped (for example, in a solid target), all of its kinetic energy is used to create a photon. What is the wavelength of this photon?
