Please write very clearly each step and submit a picture of your work. I find it very hard to understandy typed up sentences of what you are doing. Thank you. I beleive it something to do wiht taking the first and second derivative of the given wavefunction but then im not sure where to go from there. 02u 1 02u 4. Starting from the classical wave equation where v is the wavenumber and assuming u (x,t)Jy(x)cos at show that time...

The time-independent Schroedinger equation is given by: − Wave functions that satisfy this equation are called energy eigenstates. a) If U=0 for all positions, this represents a free particle. For a wave function with definite momentum ℏ,, compute E. b) Is the relationship derived from a) consistent with what we know from classical mechanics for a free particle? Explain how or how not. c) Consider the wave function ((^b[j + ^bâj), with A some number and c, d not equal...

2. The hydrogen atom [8 marks] The time-independent Schrödinger equation for the hydrogen atom in the spherical coordinate representation is where ao-top- 0.5298 10-10rn is the Bohr radius, and μ is the electon-proton reduced mass. Here, the square of the angular momentum operator L2 in the spherical coordinate representation is given by: 2 (2.2) sin θー sin θ 00 The form of the Schrödinger equation means that all energy eigenstates separate into radial and angular motion, and we can write...
Please answer the question in full and show all work. We have seen that the absolute square of the wave function VI,t) can be interpreted as the probability density for the location of the particle at time t. We have also seen that a particle's quantum state can be represented as a linear combination of eigenstates of a physical observable Q: V) SIT) where Q n ) = qn|n) and represents the probability to find the particle in the eigenstate...
