A Simplification for Electrons

Because we know the values of Planck’s Constant and the electron’s mass, we can use them to simplify the equation to apply only to electrons as

 

 or

   [ELECTRONS ONLY]

where the kinetic energy has been measured in electron volts (eV). The result, l, is the electron’s wavelength in units of nanometers. This equation works only for electrons, so use it carefully.

How does the relationship between energy and wavelength in this formula compare with the relationship that you observed with simulated electron interference?
