Harmonic Oscillator 9. An ideal harmonic oscillator has energy levels separated by a constant 0.05 eV. That is, the difference between the ground state and the first excited state of this oscillator is an energy of 0.05 eV. This single oscillator is brought into contact with a large solid composed of an enormous number of oscillators, and characterized by a temperature of T=150 K. What is the probability that the single oscillator will be found in its first excited state? 1. 0.021 2. 0.055 3. 0.098 4. 0.144 5. 0.234 6. 1.000 What relationship should I even start with? Thanks for the help!
