Calculate the ground state energy of a harmonic oscillator with a classical frequency of 3.68  1015 Hz. (1 eV = 1.60  10-19 J, h = 1.055  10-34 J  s, h = 6.626  10-34 J  s)
 
  A) 7.62 eV
  B) 15.2 eV
  C) 11.4 eV
  D) 5.71 eV

Question 2

An 80-eV electron impinges upon a potential barrier 100 eV high and 0.20 nm thick.
 
  What is the probability the electron will tunnel through the barrier? (1 eV = 1.60  10-19 J,
  mproton = 1.67  10-27 kg, h = 1.055  10-34 J  s, h = 6.626  10-34 J  s)
  A) 0.011
  B) 1.1
  C) 0.11
  D) 1.1  10-4
  E) 7.7  10-10
