Determine the average value of yn?(x) inside the well for the infinite square-well potential for n = 1, 9, 18, and 180. (v1?(x)) (492(x)) (v18(x)) (4 1802(x)) Compare these averages with the classical probability of detecting the particle inside the box. (Select all that apply.) The quantum mechanical probability is uniform throughout the box. The average value of yn 2(x) is the same as the classical probability. The classical probability depends upon n. The average value of yn?(x) depends upon...
The particle of mass m in the infinite square well (of width a) starts out of the left half of the well, and is (at 1-0) equally likely to be found at any point in that region, what is the initial wave function Ψ(0)? Assume it is real, do not forget to normalize it.

Exercise 5 Consider a particle in an infinite square well of length a. The particle is initially in the ground-state. The width of the potential well is suddenly changed by moving the right wall of the well from a to 2a. What is the probability of observing the particle in the ground-state of the new expanded well ?

An infinite square well and a finite square well in 1D with
equal width. The potential energies of these wells are
Infinite square well: V(x)=0, from 0 < x < a, also V(x) =
