Problem 8.5: Rank the wave packets according to momentum, kinetic energy, and total energy.


Please wait for the animation to completely load.

Shown are 5 different free quantum-mechanical packets. The top panel shows phase as color and the bottom panel shows the real and imaginary parts of the wave function.  In the animation, ħ = 2m = 1.

Rank the packets according to:

  1. their momentum (meaning <px>)
  2. their kinetic energy (meaning <T>)
  3. their total energy (meaning <E> = <H>)
