The structure of a wave is quite simple and can be easily understood. The features of a wave include: wavelength, amplitude, height of wave, crest and trough. But there are also other terminologies that are referred to waves - frequency, pitch, volume, velocity and period.
*Note: the dotted line in the diagram above is the wave's resting position.
Wavelength: the distance between two crests or troughs. Wavelength can be written as λ (lambda). It is not the unit that measures wavelength!
Height of Wave: the distance from the crest to the trough
Amplitude: the distance from the tip of the crest or trough to the rest position. The higher the amplitude, the higher the volume. Amplitude can be written as 'a'.
Crest: the highest point of a wave (a peak)
Trough: the lowest point of a wave
Frequency: the number of waves created in one minute. It is measured in Hertz (Hz). One Hertz equal to one vibration per second. Pitch is determined by the frequency of a wave. A high-pitched sound will have a high frequency.
Period: the time for one wave to pass through a point (from crest to crest / trough to trough)
Velocity: refers to the speed and direction of the wave
