# Components of a wave

A wave is formed by some basic components which are:

Being A to wave amplitude.

It is called wavelength, and expressed by the Greek letter lick (λ), the distance between two ridges or two consecutive valleys.

We call wave period (T) the time elapsed before two consecutive ridges or valleys pass a point and wave frequency (f) the number of consecutive ridges or valleys that pass through the same point in a given unit of time.

Therefore, the period and frequency are related by:

The internationally used unit for frequency is Hertz (Hz) where 1Hz is equivalent to passing a ridge or valley in 1 second.

For the study of two-dimensional and three-dimensional waves the concepts of:

• wave front: it is the border of the region not yet reached by the wave with the region already reached;
• wave radius: You can define the wave radius as the line that starts from the source and is perpendicular to the wavefronts, indicating the direction and direction of propagation.
