  1. 1

    What is the key difference between classical and quantum harmonic oscillators?

    • AClassical oscillators have continuous energy levels, while quantum oscillators have discrete energy levels.
    • BClassical oscillators are described by wave functions, while quantum oscillators are described by classical mechanics.
    • CClassical oscillators experience zero-point energy, while quantum oscillators do not.
    • DClassical oscillators have discrete energy levels, while quantum oscillators have continuous energy levels.
  2. 2

    What is the significance of the zero-point energy in a quantum harmonic oscillator?

    • AIt represents the minimum energy the oscillator can possess, even at absolute zero temperature.
    • BIt is an arbitrary constant that can be ignored.
    • CIt represents the minimum potential energy of the oscillator.
    • DIt is the energy the oscillator has when it is at rest.
  3. 3
