1. The problem statement, all variables and given/known data
Like ordinary wave, a particle’s wave function can be described as countless line of sine wave’s superposition. However it can also be clarified as vibration (the complex amplitude still follow the rule of local conservation) I think these two explanation are equal. Am I wrong? You can regard it as wave superposition and use Fourier transform to calculate the momentum P. However, if you regard it as vibration, how to do it?
2. Relevant equations
3. The attempt at a solution

This's the first time I have used this forum.There are some complex equations in the description of the question.So I use an image.The main description about the question is in the image.
