Path Integral doubt

  1. Dec 13, 2008 #1
    I just read the chapter in Shankar regarding path integrals (the 8th)
    I didnt quite get how he deduced that destructive interference in the summation
    sets in after S/h>pi.(This is the first section itself)
    I couldnt find reference to such a thing elsewhere.
