When a particle of energy E hits the boundary of a step potential of potential V0>0 at x=0, when is the probability that it will get reflected greater than 0 (that is, R>0)?

A.Always

B.Only if E>V0

C.Only if the potential step is positive (that is, V=0 for x<0, V=V0 for x>0)

D.Only if the potential step is negative (that is, V=V0 for x<0, V=0 for x>0)

E.Never

Only if E<V0
