Quantum Physics

This course is a part of Physics, a 20-course Topic series from Khan Academy.

Do you want to describe the microscopic world of atoms and nuclei? Well, classical physics isn't going to cut it. You'll need quantum physics to explain things like atomic energy levels, photons, and the wavelength of electrons.

This course contains 4 segments:

Photons

Light can have wave-like or particle-like properties depending on the experiment being done. These "particles" of light are called photons. In this tutorial you'll learn about photon energy and momentum.

Atoms and electrons

Sometimes people draw atoms like little solar systems, but they're way stranger than that. In this section you'll learn how electrons can have wavelengths, jump orbitals, and emit photons while in an atom.

Quantum numbers and orbitals

In this tutorial, we will see how the quantum numbers predict the orbitals available in different energy levels.

Nuclei

In this tutorial, we will learn about radioactive decay, nuclear stability, and what is happening on a subatomic level during a nuclear reaction.
