A sine wave or sinusoid is a waveform whose graph is identical to the generalized sine function Waveform quite literally means the shape and form of a signal, such as a wave moving across the surface of water, or the vibration of a plucked string. ...
In mathematics, the trigonometric functions are functions of an angle, important when studying triangles and modeling periodic phenomena. ...
- y = Asin[ω(x − α)] + C
where A is the amplitude, ω is the angular frequency (2π/P where P is the wavelength), α is the phase shift, and C is the vertical offset. Amplitude is a nonnegative scalar measure of a waves magnitude of oscillation. ...
Angular frequency is a measure of how fast an object is rotating In physics (specifically mechanics and electrical engineering), angular frequency ω (also called angular speed) is a scalar measure of rotation rate. ...
The wavelength is the distance between repeating units of a wave pattern. ...
Waves with the same phase Waves with different phases The phase of a wave relates the position of a feature, typically a peak or a trough of the waveform, to that same feature in another part of the waveform (or, which amounts to the same, on a second waveform). ...
This wave pattern occurs often in nature, including in ocean waves, sound waves, and light waves. A wave is a disturbance that propagates, carrying energy. ...
Waves Ocean surface waves are surface waves which occur at the surface of an ocean. ...

Prism splitting light Light is electromagnetic radiation with a wavelength that is visible to the eye or, in a technical or scientific setting, electromagnetic radiation of any wavelength. ...
A cosine wave is also said to be sinusoidal, since it has the same shape but is shifted slightly behind the sine wave on the horizontal axis: A Plot I made with Gnuplot and manually improved the labeling on. ...
In mathematics, the trigonometric functions are functions of an angle, important when studying triangles and modeling periodic phenomena. ...
Any non-sinusoidal waveforms, such as square waves or even the irregular sound waves made by human speech, are actually a collection of sinusoidal waves of different periods and frequencies blended together. The technique of transforming a complex waveform into its sinusoidal components is called Fourier analysis. Non-sinusoidal waveforms are waveforms that are not sine waves. ...
A square wave is a kind of basic waveform. ...

Periodicity is the quality of occurring at regular intervals (e. ...
Sine waves of various frequencies; the lower waves have higher frequencies than those above. ...
Harmonic analysis is the branch of mathematics which studies the representation of functions or signals as the superposition of basic waves. ...
The human ear can recognize single sine waves because they sound "clean" or "clear" to us; some sounds that approximate a pure sine wave are whistling, a crystal glass set to vibrate by running a wet finger around its rim, and the sound made by a tuning fork. A left human ear. ...
Whistling is the production of sound by means of a constant breath of air from the mouth. ...
The materials definition of a glass is a uniform amorphous solid material, usually produced when a suitably viscous molten material cools very rapidly, thereby not giving enough time for a regular crystal lattice to form. ...
A tuning fork is a simple metal two-pronged fork with the tines formed from a U-shaped bar of elastic material (usually steel). ...
To the human ear, a sound that is made up of more than one sine wave will either sound "noisy" or will have detectable harmonics. In acoustics and telecommunication, the harmonic of a wave is a component frequency of the signal that is an integral multiple of the fundamental frequency. ...
