Homework Help: A Question of De Broglie Waves?

  1. Oct 10, 2004 #1
    The problem states: By what percentage willl a non-relativistic calculation of the de Broglie wavelength of a 100-keV electron be in error? To start off the problem, I calculated the non-relativistic wavelenght to be .124 m? If that number is correct, how do i move on?

    Can anyone explain the basic premise of the problem to me? I'm not asking for you to solve anything, just to get me off on the right track.
