In the 'Particle in a box' system, with the well being extremely narrow, why does the particle path have to follow certain energy levels compared to the classical system?
Thanks in advance.
Thanks in advance.

Little hard spheres or soft water waves to name two extremes. The 'thingy' (electron, photon, baseball, Jupiter) does not act. It is our metaphor for describing its behaviour that is deficient and lures us towards imagining behaviour that is characteristic for phenomena we know from daily life.
And don't worry -- everyone entering this strange world of quantum mechanics is looking for this kind of mental support. After a while you learn to enjoy the astounding power and success of this theory without worrying too much about the 'why' and 'how'.
A potential well is a region in space where a particle experiences a force that is directed towards the center of the well. This force creates a potential energy that is dependent on the position of the particle within the well.
The energy levels in a potential well determine the allowed energies that a particle can have while confined in the well. The particle can only occupy these discrete energy levels and cannot have energies in between them.
The shape of a potential well affects the energy levels of a particle by determining the potential energy at different positions within the well. A deeper well will have lower energy levels, while a shallower well will have higher energy levels.
Yes, a particle can have different energy levels in a potential well. The allowed energy levels are determined by the quantum mechanical properties of the particle and the shape of the potential well.
The energy levels in a potential well are related to the probability of finding a particle in a specific energy state. The higher the energy level, the lower the probability of finding the particle in that state. The lowest energy level, known as the ground state, has the highest probability of containing the particle.
