### About this unit

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.AP® is a registered trademark of the College Board, which has not reviewed this resource.
