Techniques and applications of quantum theory

Quantum theory, often known as quantum physics, is the foundation of modern physics and encompasses the nature and behavior of matter and energy at the atomic and molecular levels. As the exact nature and behavior of atomic and subatomic particles are impossible to determine, the laws of classical physics do not apply to this discipline. As a result, quantum field theory is primarily based on assumptions and probabilities.

Question

For a quantum mechanical harmonic oscillator,
i) calculate the expectation value of the potential energy and kinetic energy in its ground and first
excited states.
ii) determine on average how much a harmonic oscillator's cenergy is kinetic versus potential in its
ground and first excited states.
