A cathode ray tube (CRT), such as those found in old-fashioned TV screens, accelerates electrons toward a screen. The electron collision with the screen emits photons. In this problem assume all of the electron kinetic energy is converted to light energy. What is the minimum wavelength of photons produced in a CRT using a 25.0-kV accelerating potential? Hint: this is a conservation of energy problem involving electrical potential energy.
