Waves Review

Front

What is the definition of wavelength?

Back

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

Front

What is amplitude in a wave?

Back

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

Front

What are the two main types of waves?

Back

Transverse waves and longitudinal waves.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the particles move 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 particles move parallel to the direction of the wave's travel.

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

How do particles move in a longitudinal wave?

Back

In a longitudinal wave, particles move closer together and then further apart.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What is the speed of a wave?

Back

The speed of a wave is the distance it travels per unit of time, calculated as speed = wavelength × frequency.
