Quantum Mechanics: Essentials

Question 1

Photon energy

Answer 1

Question 2

Photon momentum

Answer 2

Question 3

Bremsstrahlung

Answer 3

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

Question 4

Compton scattering

Answer 4

Question 5

Heisenberg Uncertainty Principle

Answer 5

Question 6

Spectrum of a gas

Answer 6

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.

Question 7

Principal quantum number

Answer 7

n - the energy level

Question 8

de Broglie wavelength

Answer 8

Question 9

Perfect black body

Answer 9

All frequencies are radiated and all frequencies are absorbed

Question 10

Quantum harmonic oscillator energy levels

Answer 10

Question 11

Expectation value

Answer 11

Question 12

Energy operator

Answer 12

Question 13

Momentum operator

Answer 13

Question 14

Infinite Square Well Energy Levels

Answer 14

Question 15

Definition of Hermitian operator

Answer 15

Question 16

Canonical commutation relation

Answer 16

Question 17

Generalized uncertainty principle

Answer 17

Question 18

Relationships which assist in calculation of commutators

Answer 18

Question 19

Commutation of angular momentum operators

Answer 19
