Physics

Atomic, Molecular & Optical Physics

Atomic physics is the field of physics that analyses atoms as an isolated system of electrons and an atomic nucleus while molecular physics is the study of the physical properties of molecules. Optical physics use and develop light sources that span the electromagnetic spectrum from microwaves to X-rays. The optical physics includes the generation and detection of light, linear and nonlinear optical processes, spectroscopy, lasers and laser spectroscopy. The three branches are closely interrelated. Naturally, the theory and applications of emission, absorption, scattering of electromagnetic radiation from atoms and molecules, analysis of spectroscopy, generation of lasers and masers, and the optical properties of matter fall into these categories.
