A parallel beam of electrons traveling in x direction falls on a slit of width d. After passing the slit an electron acquires momentum P(y) in the y direction then for a majority of electronselectrons passing through the slit (h is the Planck's constant )-
(a) |P(y)|d >h
(b) |P(y)|d >>h
(c) |P(y)|d = h (nearly equal)
(d) |P(y)|d < h
