Parts and properties of waves test review

A wave is a disturbance that transfers energy from one place to another without transferring matter.

The two main types of waves are mechanical waves (which require a medium) and electromagnetic waves (which do not require a medium).

Amplitude is the maximum height of a wave from its rest position, indicating the energy of the wave.

Wavelength is the distance between two consecutive points that are in phase on a wave, such as crest to crest or trough to trough.

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).

Higher amplitude means more energy; therefore, a wave with a larger amplitude carries more energy.

Compressions are regions in a longitudinal wave where particles are close together.

Rarefactions are regions in a longitudinal wave where particles are spread apart.

The higher the amplitude of a sound wave, the louder the sound; lower amplitude results in a quieter sound.

Wave speed = frequency × wavelength.
