Schrodinger equation in a well question?

In summary, the conversation discusses a homework problem that involves finding a wave function inside and outside a well and meeting certain boundary conditions. The Wilson-Sommerfeld quantization condition must be applied, and the author suggests searching for information on this topic online or in course notes. The importance of the particle being classical is also mentioned, with a note indicating that something is expected to happen in the working.

The Attempt at a Solution


I'm not even sure where to start :( I'm assuming that i have to find a wave function outside and inside the well and meet certain boundary conditions, but I am confused. Please help.

You are supposed to apply the Wilson-Sommerfeld quantization condition.
If you don't know what that is, your first step will be to find out.
You can do this by hunting through your lecture or course notes, or searching online.

Aside: what is important about the particle being classical that the author felt the need to put word "classical" in bold face? What does the "NB" note tell you to expect to happen someplace in your working?

Good luck.

1. What is the Schrodinger equation in a well?

The Schrodinger equation in a well is a mathematical equation that describes the behavior of a particle in a potential well, such as a particle trapped in a box or a particle bound to an atom. It is a fundamental equation in quantum mechanics and is used to predict the probability of finding a particle in a certain location.

2. How does the Schrodinger equation in a well differ from the free particle Schrodinger equation?

The Schrodinger equation in a well takes into account the potential energy of the particle due to its confinement in a well, while the free particle Schrodinger equation assumes that the particle has no potential energy. This results in different solutions and predictions for the behavior of the particle.

3. Can the Schrodinger equation in a well be solved analytically?

Yes, the Schrodinger equation in a well can be solved analytically for certain types of potential wells, such as the infinite square well or the harmonic oscillator. However, for more complex potential wells, numerical methods are often used to approximate the solutions.

4. What is the physical significance of the solutions to the Schrodinger equation in a well?

The solutions to the Schrodinger equation in a well represent the allowed energy levels and corresponding wavefunctions of a particle trapped in a potential well. These energy levels and wavefunctions can be used to calculate the probabilities of various outcomes, such as the position or momentum of the particle.

5. How does the Schrodinger equation in a well relate to the Heisenberg uncertainty principle?

The Schrodinger equation in a well is a solution to the time-dependent Schrodinger equation, which is a fundamental equation in quantum mechanics. The Heisenberg uncertainty principle is a consequence of the wave-like nature of particles described by the Schrodinger equation, and it states that it is impossible to simultaneously know the exact position and momentum of a particle. The solutions to the Schrodinger equation in a well reflect this uncertainty in the position and momentum of the trapped particle.
