Particle in a well potential/energy continuity

  1. Nov 26, 2015 #1
    Hello again,
    Am facing a difficulty, the question is that ,
    Is energy and momentum conserved for a particle in an infinite square well, at the boundary i.e, at x=a, where the potential suffers an infinite discontinuity??
    V=0 for -a<=x<=a
    V=infinite else-where
    Thanks in advance :smile:

    Yes it is. The particle can't penetrate an infinitely high potential barrier, so it completely reflects there. (provided this isn't classical mechanics with an inelastic collision!)
