For these graphs, they are wave functions of identical particles
that are within an infinite square well and their width is a.
a.)What is the most probable value of the energy for each wave
function and which state has the largest probable energy?
b.) Which of these states has the largest expectation value of
the energy? (this part can be done without calculating the
expectation value of the energy)
