Lecture: 30 (iq27)
1. Comments on selected topics in Energy Quantization:
o Absorption of a photon when
there is a match in energies
o Temperature dependence on
the population of excited states
o Quantum harmonic oscillators
o Level gaps to charge
interactions vs level gaps due to dipole interactions
2. The center of mass in the multiparticle
system
o Momentum principle applied
to the point system.
o Energy principle applied to
the point system.
3. Energy principle applied to the real system: Ktotal=Kcm+Krot+ …
o Example: Two hockey pucks.
4. Rotational kinetic energy: Krot
and moment of inertia:
o Example: Two hockey pucks. Express
d’ in terms of d
