While two superimposed sinusoidal waves, called a bichromatic wave, have an envelope which travels unchanged, three or more sinusoidal wave components result in a changing pattern of the waves and their envelope.

Since the uncertainty ( and hence measurement noise ) stays constant at as the amplitude of the oscillation increases, the state behaves more and more like a sinusoidal wave, as shown in Figure 1.

A sea state that is : real waves on the sea or ocean can be described as a superposition of many sinusoidal waves with different wavelengths, amplitudes, initial phases and propagation directions.
35.
The specific case of playing sinusoidal waves of different frequencies, which creates a continuously varying sensation of the sound source moving from side-to-side, is referred to as a binaural beat.
36.
The transmitted wave cannot, however, be a sinusoidal wave, since it would then transport energy away from the boundary, but since the incident and reflected waves have equal energy, this would violate conservation of energy.

With respect to the AC-sensitive terms, tabular presentation of the NM equation results in the National Electrical Code was developed assuming the standard North American power frequency of 60 hertz and sinusoidal wave forms for current and voltage.
38.
In particular, many media are linear, or nearly so, so the calculation of arbitrary wave behavior can be found by adding up responses to individual sinusoidal waves using the superposition principle to find the solution for a general waveform.
39.
The energy density ( per unit area ) of regular sinusoidal waves depends on the water density \ rho, gravity acceleration g and the wave height H ( which, for regular waves, is equal to twice the amplitude, a ):

While it is true that electronically produced periodic tones ( e . g . square waves or other non-sinusoidal waves ) have " harmonics " that are whole number multiples of the fundamental frequency, practical instruments do not all have this characteristic.
