Round 7: Tossup 1

For a particle in a box, this quantity equals n-squared times pi-squared times h-bar-squared, all divided by 2 m L squared. (10[1])This quantity is respectively raised and lowered (-5[1])by operators denoted a-plus and a-minus. (10[1])This quantity is an eigenvalue of the time-independent Schrödinger equation, which states that this quantity times (10[1])psi equals the Hamiltonian times psi. (10[1])A form of the uncertainty principle relates the uncertainties of time and this quantity. (10[1]-5[2])Max (-5[1])Planck postulated that a photon’s value of this quantity (-5[1])equals h times frequency. (-5[1])This quantity (-5[1])is minimized in the ground state. For 10 points, what quantity can be divided into “kinetic” and “potential” forms? (10[1])■END■ (10[6])
