Waves

Front

What is the definition of wavelength?

Back

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

Front

What does amplitude represent in a wave?

Back

Amplitude is the maximum distance that points on a wave, such as crests and troughs, move from their rest position.

Front

What are the two main parts of a longitudinal wave?

Back

The two main parts of a longitudinal wave are compressions and rarefactions.

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

What is compression in a longitudinal wave?

Back

Compression is the region in a longitudinal wave where particles are closest together.

Front

What is rarefaction in a longitudinal wave?

Back

Rarefaction is the region in a longitudinal wave where particles are spread apart.

Front

How does wavelength affect wave speed?

Back

In a given medium, wave speed is directly proportional to wavelength; as wavelength increases, wave speed increases.

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 formula for wave speed?

Back

Wave speed (v) = frequency (f) × wavelength (λ).
