- Show that the probability associated with the state Ψn for a particle in a one- dimensional box 0≤ x≤ L obeys the following relationship: (You can see the picture attached for the problem)1) a) A particle is in an infinite square well, with ground state energy E1. The wavefunction is 3 *y. Find in terms of E1. (There is an easy way to do this; no actual integrals 4 + 5 required.) b) A particle is in an infinite square well, with ground state energy Ej. Find a normalized wavefunction that has a total energy expectation value equal to 3E1. (It will be a superposition.) Keep all your coefficients real and positive. c) Now time-evolve your answer from part b, to show how the wavefunction varies with time.Notice for the finite square-well potential that the wave function Ψ is not zero outside the well despite the fact that E < V0. Is it possible classically for a particle to be in a region where E < V0? Explain this result
