Quantum mechanics lessons

Learn what Hermitian operators and matrices are and what three important properties they have. Examples are also made.

List of important physical quantities, their symbols, (derived) units and examples with images.

Here you will learn how to determine energy of photons and how this energy depends on the color of light (frequency or wavelength).

Here you will learn how the photoelectric effect is explained quantum mechanically, how the stopping voltage method works and everything else you need to know.

Learn about important physical constants and what their formula symbols and SI units are.

In this lesson you will learn about the time-dependent and independent Schrödinger equation (1d, 3d), how it is derived and what you can do with it.

Here you will learn about angular momentum in quantum mechanics, its commutators, and how angular momentum states and eigenvalues are generated using ladder operators.

Here you will learn about matter waves and how they are characterized by the de Broglie wavelength (matter wavelength).

Here you will learn how Bra-Ket notation (Dirac notation) is defined, which computational rules exist for it and which advantages this notation brings.
