Noun
standing wave (plural standing waves)
(physics) A wave form which occurs in a limited, fixed medium in such a way that the reflected wave coincides with the produced wave. A common example is the vibration of the strings on a musical stringed instrument.
An impedance mismatch creates a reflected wave, which added to the incoming waves creates a standing wave. Source: Internet
A post-exposure bake (PEB) is performed before developing, typically to help reduce standing wave phenomena caused by the destructive and constructive interference patterns of the incident light. Source: Internet
A standing wave (black) depicted as the sum of two propagating waves traveling in opposite directions (red and blue) Standing waves A standing wave is an undulatory motion that stays in one place. Source: Internet
A standing wave on a disk with two nodal lines crossing at the center; this is an overtone. Source: Internet
A standing wave like this can have 0,1,2, or any integer number of wavelengths around the circle, but it cannot have a non-integer number of wavelengths like 8.3. Source: Internet
For example: a wave traveling to the right along a taut string and hitting the end will reflect back in the other direction along the string, and the two waves will superpose to produce a standing wave. Source: Internet
