A beam of 12 eV electrons is incident on a potential barrier of height 30 eV and wit 0.05 nm. Calculate the transmission coefficient?

Show that electron pressure at T = 0 is: P = 2.N.Ef/5.V Does it makes sense to have pressure at 0 kelvin?

A particle is confined in a box of length L.  The momentum is quantized and we find that the lowest possible value of the momentum for a particle in that box is 1.3 E-24 kg.m2/s. What is the length of the box? Express your answer in Angstroms (1E-10 m)

An electron is trapped in an infinitely deep one-dimensional well of width 0,251 nm. Initially the electron occupies the n=4 state. Suppose the electron jumps to the ground state with the accompanying emission of photon. What is the energy of the photon?

An electron is confined between two perfectly reflecting walls separated by the distance 12 x 10-11m. Use the Heisenberg uncertainty relation to estimate the lowest energy that the particle can have (in eV).

A Proton is confined to move in a one- dimensional bux of length 0.410 m a) Find the lowest possible energy of the proton. Note: Answer must be in ev

An initially stationary electron is accelerated through a voltage 93.6 eV. What is it's de Broglie wavelength, in pm?

(x, t) = Ae-iwt e-(mw/ħ).x² which is a solution to Schrödinger's equation. Determine the potential V(x) that is consistent with this wave function, Note: You do not have to normalize V since Schrödinger's equation is linear.
