Problems
Comparing classical electromagnetic waves with photon probability waves.
Problem 1 refers to: A standing electric field wave (one with lots of photons) in a quantum wire stretching between x = 0 and x = L is described by E(x,t)=Emaxsin(3πx/L)cos(3πct/L). Let L = 900 nm.

A little E&M practice
Problems 1-2 refer to: The electric field in a laser beam is given by E( x,t) = (1000V/m)sin[(πx107rad/m) x + (3πx1015rad/s)t].

Problems
A bit of stat mech
Problems 1-3 refer to: N identical, noninteracting, and distinguishable spin-1/2 particles (i.e., their separation is much greater than their de Broglie wavelength) are placed in an external magnetic field. Assume the ground state energy of one such particle is 0 and the excited state energy is ε , and the system is in thermal equilibrium at temperature T.

Problems
A little energy and momentum practice (and units)
Problems 1-2 deal with “rest” energy and relativity.

Problems
Another bit of stat mech
Problems 1-3 refer to: N identical, noninteracting, and distinguishable quantum harmonic oscillators (i.e., their separation is much greater than their de Broglie wavelength) are in thermal equilibrium at temperature T. The energy of each oscillator can be expressed as εn = nε , where ε is the level spacing and n = 0, 1, 2, … .
