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

Transverse waves and longitudinal waves.

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 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 amplitude?

Back

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

Front

What is wavelength?

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 frequency?

Back

The number of waves that pass a given point in a certain amount of time, usually measured in Hertz (Hz).

Front

What is the relationship between frequency and wavelength?

Back

As frequency increases, wavelength decreases, and vice versa, when the speed of the wave is constant.

Front

What is a mechanical wave?

Back

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

Front

What is a vacuum?

Back

A space that is completely empty of matter, where mechanical waves cannot travel.
