Tossup

For a particle in a box, this quantity equals n-squared times pi-squared times h-bar-squared, (10[2])all divided (10[1])by 2 (10[1])m L squared. This quantity is respectively raised and lowered by operators denoted a-plus and a-minus. This quantity is an eigenvalue of the time-independent Schrödinger equation, which states that this quantity times psi equals the Hamiltonian times psi. A form of the uncertainty principle relates the uncertainties of time and this (10[1]-5[1])quantity. (10[1]-5[1])Max Planck (-5[1])postulated (-5[1])that a photon’s value (10[1])of this quantity equals h times frequency. This quantity is minimized in the ground state. For 10 points, what quantity can be divided into “kinetic” and “potential” forms? ■END■ (10[3])

ANSWER: energy [accept total energy, kinetic energy, or potential energy; accept energy level; prompt on Hamiltonian until read by asking “what physical quantity does that represent?”]
