Front

What is sound?

Back

Sound is a type of wave that is produced by vibrating objects and travels through a medium such as air, water, or solids.

Front

What is a rarefaction in a wave?

Back

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

Front

What is a compression in a wave?

Back

A compression is a region in a longitudinal wave where the particles are close together.

Front

What type of wave is a sound wave?

Back

A sound wave is a longitudinal wave.

Front

What does pitch refer to in sound?

Back

Pitch refers to how high or low a sound is, which is determined by the frequency of the sound wave.

Front

What is frequency?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz).

Front

What is amplitude?

Back

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

Front

How does increasing amplitude affect sound?

Back

Increasing amplitude makes the sound louder.

Front

What is the relationship between frequency and pitch?

Back

Higher frequency results in a higher pitch, while lower frequency results in a lower pitch.
