In this video I will explain the particle in a finite well instead of an infinite well. Which means the barriers does not have infinite height or energy. In quantum mechanics that means the particle can venture outside of the trapped region. For example if region 1 is the barrier on the left-side, region 3 is the barrier on the right-side, and region 2 is in the middle where the particle is located, and if the barrier is infinite in height that means it'll require an infinite amount of energy for the particle to cross the barrier into regions 1 and 3. However if the energy required to cross into regions 1and 3 is finite, then the particle can reside in region 1 or 3. (Part 1)
