Properties of waves

Front

What is a wave?

Back

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

Front

What are the two main types of waves?

Back

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

Front

What is frequency in relation to waves?

Back

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

What is amplitude?

Back

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

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

How does energy relate to amplitude?

Back

Higher amplitude means higher energy; a wave with greater amplitude carries more energy.

Front

What is the wavelength of a wave?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

What is a mechanical wave?

Back

A mechanical wave is a wave that requires a medium (solid, liquid, or gas) to travel through.
