Coherent light is passed through two narrow slits whose separation is 20.0 mm. The second-order bright fringe in the interference pattern is located at an angle of 0.0300 rad. If electrons are used instead of light, what must the kinetic energy (in electron volts) of the electrons be if they are to produce an interference pattern for which the second-order maximum is also at 0.0300 rad?

Question
Coherent light is passed through two narrow slits whose
separation is 20.0 mm. The second-order bright fringe in the interference
pattern is located at an angle of 0.0300 rad. If electrons are used
instead of light, what must the kinetic energy (in electron volts) of the
electrons be if they are to produce an interference pattern for which the
second-order maximum is also at 0.0300 rad?
