There are several key terms associated with waves:

 

• Amplitude: The height or distance from the rest position of a wave's crest or trough.

 

• Frequency: The number of wave cycles (crests and troughs) passing a point in one second, measured in Hertz (Hz).

 

• Wavelength: The distance between two consecutive points in a wave with the same phase, such as two crests or two troughs.

 

• Period: The time it takes for one complete wave cycle to pass a point.
