for a particle in a square box of side L, at what position is the probability density a maximum if the wave function has n1=1, n2=3? also describe the position of any node or nodes in the wave function.
Homework Answers
i am not solve for tha
maximum.probablity value. If you want the value of adject value of
probability please intergrate equation 1 and 2 in limit 0 to L
.
If any doubt please comment in comment box. Thank you have a nice day
