Quantum Mechanics: Essentials Flashcards
Photon energy

Photon momentum

Bremsstrahlung
“Braking radiation”. Electromagnetic radiation produced by the deceleration of one charged particle by another charged particle.
Compton scattering

Heisenberg Uncertainty Principle

Spectrum of a gas
The spectrum of a gas is discrete, and is called an emission line spectrum. Each line is a spectral line. A heated gas selectively emits photons, while a cold gas selectively absorbs. The emission and absorption spectrum are the same.
Principal quantum number
n - the energy level
de Broglie wavelength

Perfect black body
All frequencies are radiated and all frequencies are absorbed
Quantum harmonic oscillator energy levels
