A photon with wavelength of 0.110 nm collides with a free electron that is initially at rest. After the collision, the photon's wavelength is 0.114 nm.
What is the kinetic energy of the electron after the collision?
K_e =
What is the speed of the electron after the collision?
upsilon_e = m/s
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?
