Suppose that electrons are accelerated through a potential difference of 80 × 103 V. These collide with a metal slab and emit electromagnetic radiation.

a) Determine the kinetic energy of an individual electron. Express the answer in Joules and electron Volts (1.0 eV = 1.6 × 10−19 J.)

b) The electron collides with the metal and a photon is emitted. Determine the maximum frequency that is possible for the emitted photon.
