Recall that |ψ|2dx is the probability of finding the particle that has normalized wave function ψ(x) in the interval x to x+dx. Consider a particle in a box with rigid walls at x=0 and x=L. Let the particle be in the first excited level and use ψn as given in equation 2L−−√sinnπxL, n = 2. A] For which values of x, if any, in the range from 0 to L is the probability of finding the particle zero?

Express your answer in terms of the variable L. Enter your answers in ascending order separated by commas.

B] For which values of x is the probability highest?

Express your answer in terms of the variable L. Enter your answers in ascending order separated by commas.
