In free space, examples of these things, which are not beams, take an HermiteÂ–Gaussian (air-MEET GOW-see-in) form and are abbreviated TEM.
In free space, examples of these things, which are not beams, take an HermiteÂ–Gaussian (air-MEET GOW-see-in) form and are abbreviated TEM. For a Gaussian beam, a measure of how far out the beam goes before the intensity drops by a factor of e-squared is this term's "field diameter". Two indices are used to define the "guided" examples of these things, abbreviated LP, which are a common object of study in the context of optical fibers. Optical fibers can be divided into those that have one of these things and those that have multiple. For a system of masses, motions in which every mass moves with the same frequency is an example of these things, which occur at integer multiples of the fundamental frequency. For 10 points, name these things that are prefixed by "normal" to indicate special motions in a coupled oscillatory system.
