Sine Wave

Sine Wave

A voltage-time graph of a sine wave. The amplitude, wavelength, peak-to-peak amplitude and r.m.s. voltage are all labelled.

a curve representing periodic oscillations of constant amplitude as given by a sine function.

All waves can be made by adding up sine waves. The sine wave has a pattern that repeats. The length of this repeating piece of the sine wave is called the wavelength. The wavelength can be found by measuring the length or distance between one peak of a sine wave and the next peak. The wavelength can be found in many other ways too.

Sine waves have a "length" called a wavelength. There are other properties of waves and sine waves, such as their frequency, amplitude, phase, and speed.

The frequency of a sine wave is the number of oscillations a wave has in a certain period of time, for example one second.

The sine wave or sinusoid is a mathematical curve that describes a smooth repetitive oscillation. It is named after the function sine, of which it is the graph. It occurs often in pure and applied mathematics, as well as physics, engineering, signal processing and many other fields.

The sine wave is important in physics because it retains its wave shape when added to another sine wave of the same frequency and arbitrary phase and magnitude. It is the only periodic waveform that has this property. This property leads to its importance in Fourier analysis and makes it acoustically unique.
