Tossup

For a particle in a box, this quantity equals n-squared times pi-squared times h-bar-squared, 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. (10[3])A form of the uncertainty principle relates the uncertainties (-5[2])of time and this quantity. Max Planck postulated that a photon’s value 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[2])
