The height of the wave at any location and time, measured from the middle, or equilibrium position is the displacement. The maximum displacement is called the amplitude. As a first approximation, water waves, electromagnetic waves and many other kinds of waves can be modeled by the mathematical functions sine or cosine or some combination of them.

The frequency of a sinusoidal function is the number of periods (or cycles) per unit time. frequency = 1 period. A mathematical model is a function that describes some phenomenon. For objects that exhibit periodic behavior, a sinusoidal function can be used as a model since these functions are periodic.
A sinusoidal transverse wave has a wavelength of 2.80 m. It takes 0.10 s for a portion of the string at a position x to move from a maximum position of y=0.03 m to the equilibrium position y=0 . What are the period, frequency, and wave speed of the wave?
For example, in Save the Waves (2004), artist Jean-Pierre Aubé uses sine waves to make a conceptual link to the sinusoidal form of alternate electrical current. Where the sine wave seems to have a significant aesthetic impact through its conceptual use, the resulting sound output is often far from its intrinsic purity.
The range of sine and cosine is the interval [-1, 1]. Both these graphs are called sinusoidal graphs. In both graphs, the shape of the graph begins repeating after 2 π π. Indeed, since any coterminal angles will have the same sine and cosine values, we could conclude that. sin(θ + 2π) = sin(θ) sin ( θ + 2 π) = sin ( θ)
