Quantum Simple Harmonic Oscillator

Click For Summary
SUMMARY

The discussion focuses on the Quantum Simple Harmonic Oscillator, specifically analyzing a macroscopic pendulum with a mass of 10 g and a length of 50 cm. The ground state energy is computed, and the quantum number for a displacement of 0.1 mm is determined to be 2.1 x 10^28. Additionally, the increase in energy for the harmonic oscillator when the pendulum is raised 0.1 mm is explored, along with the corresponding excited-state energy levels.

PREREQUISITES
  • Understanding of quantum mechanics principles, particularly harmonic oscillators.
  • Familiarity with energy quantization in quantum systems.
  • Knowledge of basic pendulum dynamics and period calculations.
  • Ability to perform calculations involving Planck's constant and energy levels.
NEXT STEPS
  • Study the derivation of the energy levels for the Quantum Simple Harmonic Oscillator.
  • Learn about the implications of quantum numbers in harmonic oscillators.
  • Explore the relationship between displacement and energy changes in quantum systems.
  • Investigate the mathematical formulation of the period of a pendulum in quantum mechanics.
USEFUL FOR

Students and educators in physics, particularly those focusing on quantum mechanics and harmonic oscillators, as well as researchers exploring macroscopic quantum phenomena.

Homework Statement


The period of a macroscopic pendulum made with a mass of 10 g suspended from
a massless cord 50 cm long is 1.42 s. (a) Compute the ground state (zero-point) energy. (b) If the
pendulum is set into motion so that the mass raises 0.1 mm above its equilibrium position, what will
be the quantum number of this state? (c) What is the frequency of motion in (b)?

Need help! I keep doing the problem but getting the wrong answers. I got A but am not getting B. the answer to B is 2.1*10^28

What are the energies of the excited states? By how much does the harmonic oscillator's energy increase when the pendulum is raised 0.1 mm? Which excited-state energy does this correspond to?
