waves and wave properties

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 longitudinal waves and transverse waves.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a wave in which the particles of the medium move parallel to the direction of the wave's propagation.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the particles of the medium move perpendicular to the direction of the wave's propagation.

Front

What is compression in a longitudinal wave?

Back

Compression is the part of a longitudinal wave where particles are packed closely together.

Front

What is rarefaction in a longitudinal wave?

Back

Rarefaction is the part of a longitudinal wave where particles are spread apart.

Front

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

What is wavelength?

Back

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

Front

What is frequency?

Back

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