Front

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

Mechanical waves and electromagnetic waves.

Front

What is the wavelength of a wave?

Back

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

Front

What is a longitudinal wave?

Back

A wave in which the particles of the medium move parallel to the direction of the wave's travel.

Front

What is a transverse wave?

Back

A wave in which the particles of the medium move perpendicular to the direction of the wave's travel.

Front

What is frequency?

Back

The number of complete wavelengths that pass a point in one second, measured in Hertz (Hz).

Front

What is amplitude?

Back

The maximum distance that the particles of a wave move from their rest position.

Front

What is a compression in a longitudinal wave?

Back

A region in a longitudinal wave where the particles are close together.

Front

What is a rarefaction in a longitudinal wave?

Back

A part in a longitudinal wave where the particles are spread apart.

Front

What is the speed of sound in air at room temperature?

Back

Approximately 343 meters per second.
