Consider electron in an infinite potential well, studied in quantum mechanics. Position probability density of the electron is
Pn(x)=(2L)sin2(nπxL)
where 0≤x≤L and L is length of the box.
So for n>1, probability density & hence probability of finding location of the electron at certain x is 0. The electron moves from left to right & right to left between the walls of the well. So Mathematics says that electron can not be found at certain x node locations within the box; which is very strange. But is there any experimental evidence for this? While crossing these special x node locations, as if electron disappears from the box. This is very absurd.
My question is: Is this a just mathematical result (without any reality) or a physical reality/actuality?
