/15 Name: 5. A photoelectron is emitted with a kinetic energy of 2.1 eV. How fast is the electron moving? (3) 6. An x-ray light source with a wavelength of 2.87 x 10-12m is shot at a piece of graphite. On the other side, the x-ray is observed to have scattered at an angle of 350 away from the original path. Determine the wavelength of the scattered x-ray. (BONUS: Determine the velocity of the ejected electron.) (3+1)
