31Square wave — A square wave is a kind of non sinusoidal waveform, most typically encountered in electronics and signal processing. An ideal square wave alternates regularly and instantaneously between two levels. Origins and uses Square waves are universally… …
32Sine wave — Sinusoid redirects here. For the blood vessel, see Sinusoid (blood vessel). The graphs of the sine and cosine functions are sinusoids of different phases. The sine wave or sinusoid is a mathematical function that describes a smooth repetitive… …
33Standing wave ratio — In telecommunications, standing wave ratio (SWR) is the ratio of the amplitude of a partial standing wave at an antinode (maximum) to the amplitude at an adjacent node (minimum), in an electrical transmission line. The SWR is usually defined as a …

37Second-wave feminism — refers to a period of feminist activity which began during the 1960s and lasted through the late 1970s. Where first wave feminism focused on overturning legal ( de jure ) obstacles to equality, second wave feminism addressed unofficial ( de facto …
38Rotating wave approximation — The rotating wave approximation is an approximation used in atom optics and magnetic resonance. In this approximation, terms in a Hamiltonian which oscillate rapidly are neglected. This is a valid approximation when the applied electromagnetic… …
39Hong Kong Mass Migration Wave — The Hong Kong Mass Migration Wave was the waves of emigration of Hong Kong residents to overseas countries since the Second World War, accelerated by the Hong Kong 1967 Leftist Riots and extending into the 1980s 90s. By some estimates, from 1980… …
