What is the amplitude of a wave?

Back

The amplitude is the maximum distance that points on a wave, such as the crest or trough, move from their rest position.

Front

What are compressions in a sound wave?

Back

Compressions are areas in a sound wave where the medium is squeezed together, resulting in higher pressure.

Front

Define 'crest' in the context of a wave.

Back

The crest is the highest point of a transverse wave.

Front

What is a trough in a wave?

Back

The trough is the lowest point of a transverse wave.

Front

What does wavelength refer to in a wave?

Back

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

Front

What is the relationship between frequency and wavelength?

Back

Frequency is inversely related to wavelength; as frequency increases, wavelength decreases.

Front

Define 'transverse wave'.

Back

A transverse wave is a wave in which the motion of the medium is perpendicular to the direction of the wave's travel.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a wave in which the motion of the medium is parallel to the direction of the wave's travel.

Front

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

Back

The speed of sound in air at room temperature is approximately 343 meters per second.

Front

How does temperature affect the speed of sound?

Back

The speed of sound increases with an increase in temperature because warmer air has more energy and allows sound waves to travel faster.
