If electrons are quantized particles that behave like waves then based on the de Broglie hypothesis their kinetic energy is well defined. (a) Determine the energy and wavelength of free electrons (electrons in vacuum or those not confined in an atom) accelerated by a potential difference of 100 kV. (b) Do the same calculation for electrons with a potential energy of 1 eV. (c) On the other hand electrons trapped in a typical solid, such as a conducting metal, have...
