Suppose an electron is accelerated from rest through a difference in potential of V = 4.6 V. The electron now collides head-on with a photon of frequency fo = 8.91x1016 Hz moving in the opposite direction. After the "collision", the photon bounces backward with frequency f' = 4.81x1016 Hz.
i. Find the speed of the electron after the collision:
v = m/s
ii. Find the energy lost (a positive number) in the collision:
Î"W = J
