Quantum Mechanics - Harmonic Oscillator

If v is frequency and h is Planck’s constant, the ground state energy of a one-dimensional quantum mechanical harmonic oscillator

A. 0
B. 1/3 hv
C. 1/2 hv
D. hv
E. 3/2 hv
(GR9277 #56)
Solution:

The energy of a 1-D quantum HO: En = (n + ½)hv

The ground state energy, n = 0 → E0 = ½ hv

Answer: C
