Waves

Front

What are longitudinal waves?

Back

Waves where vibrations run parallel to the direction of wave travel, such as sound waves.

Front

What are transverse waves?

Back

Waves where vibrations run perpendicular to the direction of wave travel, such as light waves.

Front

What is frequency?

Back

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

Front

If 100 waves pass a point in 4 seconds, what is the frequency?

Back

25 Hz.

Front

What is amplitude in a wave?

Back

The maximum distance from the rest position to the crest or trough of the wave.

Front

What is a crest in a wave?

Back

The highest point of a transverse wave.

Front

What is a trough in a wave?

Back

The lowest point of a transverse wave.

Front

What is wavelength?

Back

The distance between two consecutive crests or troughs in a wave.

Front

What are examples of longitudinal waves?

Back

Sound waves and earthquake P-waves.

Front

What is a compression in a wave?

Back

A region in a longitudinal wave where particles are closest together.
