Question

Consider a finite potential step with V = V₀ in the region x < 0, and V = 0 in the region x > 0 (image).

For particles with energy E > V₀, and coming into the system from the left, what would be the wavefunction used to describe the “transmitted” particles and the wavefunction used to describe the “reflected” particles?

E >Vo
region 1
region 2
V = Vo

A particle is confined to a one dimensional box with boundaries at x=0 and x-1. The wave function of the particle within the box boundaries is V(x) 2100 (- x + ) and zero V 619 everywhere else. What is the probability of finding the particle between x=0 and x=0.621? Do not enter your final answer as a percentage, but rather a number between 0 and 1. For instance, if you get that the probability is 20%, enter 0.2.
An electron with an initial kinetic energy of 1.542 eV (in a region with 1.095 eV potential energy) is incident on a potential step (extending from x=0 to ∞) to V=2.381 eV. What is the transmission probability (in %)? FYI: If we had a travelling wave arriving at a similar potential DROP, then k1 (for x<0) would be real and the symmetry of R=(k1-k2)2/(k1+k2)2 implies reflection/transmission are the same as a potential RISE with the same energies but k1 and k2 swapped.

Imagine that the horizontal box shown is instead oriented vertically. Also imagine the box to be on a neutron star where the gravitational field is so strong that the particle in the box slows significantly, nearly stopping, before it hits the top of the box. Make a qualitative sketch of the n = 3 de Brogliestanding wave of a particle in this box.Hint: The nodes are not uniformly spaced.
The potential energy of a harmonic oscillator is U = kx. Show that the expectation value (U) of U is E0 / 2 when the oscillator is in the state n = 0. (In fact, this is true for all states of the harmonic ocillator.) What is the expected value of the kinetic energy of the oscillator? How do these results compare to the classical values of Ū and KE ?
