Atomic, molecular, and optical physics Atomic, molecular, and optical physics Atomic, molecular, and optical physics (AMO) is the study of matter-matter and light-matter interactions; at the scale of one or a few atoms and energy scales around several electron volts. The three areas are closely interrelated. AMO theory includes classical, semi-classical and quantum treatments. Typically, the theory and applications of emission, absorption, scattering of electromagnetic radiation (light) from excited atoms and molecules, analysis of spectroscopy, generation of lasers and masers, and the optical properties of matter in general, fall into these categories. Atomic physics is the subfield of AMO that studies atoms as an isolated
Voyage to the Bottom of the Sea radiation belts had only recently been discovered, and much of what the film says about them is made up for the film. Discoveries since then clearly invalidate what the film says: the Van Allen belts (actually somewhat more radiation-dense portions of the magnetosphere) are made up of sub-atomic particles trapped by the Earth's magnetic field in the vacuum of space and cannot catch fire, as fire requires oxygen, fuel and an ignition source, all of which are insufficient in the Van Allen Belts. Unburned hydrocarbon emissions have never reached concentrations that could support a "skyfire." The film's submarine design is
