Abstract:
So-called single-mode fibers are generally bimodal in that they can propagate two modes with orthogonal polarizations. If both transverse offset and angular misalignment are present in a single-mode fiber connector, the loss will be mode dependent. Physical distortions of the fiber before a connector cause modal noise. It is shown that the signal-to-noise ratio caused in this way is of the same order of magnitude as in suitable multimode-fiber systems.

01:03Modes of Standing Waves - I
A close look at earthquakes provides evidence for the conditions appropriate for resonance, standing waves, and constructive and destructive interference. A building may vibrate for several seconds with a driving frequency matching the building's natural frequency of vibration; this produces a resonance that results in one building collapsing while the neighboring buildings do not. Often, buildings of a certain height are devastated, while other taller buildings remain intact. This phenomenon...

Electromagnetic waves are consistent with Ampere's law. Assuming there is no conduction current Ampere's law is given as:
00:53Sound Waves: Interference
Sound waves can be modeled either as longitudinal waves, wherein the molecules of the medium oscillate around an equilibrium position, or as pressure waves. When two identical waves from the same source superimpose on each other, the combination of two crests or two troughs results in amplitude reinforcement known as constructive interference. If two identical waves, that are initially in phase, become out of phase because of different path lengths, the combination of crests with troughs...
