# Infinite potential well

I've been told about the infinite potential well using quantum-mechanics, with mathematical proof. Is there any websites I can look at to understand this theory with less math, but instead, with a theoratical approach? Would classical-physics be able to describe this result?

thanks

The concept of an infinite potential is taken to simply mean an impenetrable boundary.

How come for some points in the 'well', the probability of finding a partical is zero?

For which points in the well is the probability of finding the particle zero? Are you referring to the points corresponding to the walls of the well?

A particle in an infinitely deep potential well is a very simple concept (well, mathematically simple...) and is a simplification of many actual things- laser cavities (or any resonant cavity), for example.

What I suspect you are asking about is that your example shows a standing wave- you have a square-bottomed well?
