Sound Waves

Front

What is a rarefaction in sound waves?

Back

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

Front

What physical property of a medium is defined by how close the particles are to each other?

Back

Density is the physical property that describes how close the particles of a substance are.

Front

What type of wave do sound waves travel as?

Back

Sound waves travel as longitudinal waves.

Front

What is the term for the amount of energy a sound wave carries per unit area?

Back

Intensity is the term for the amount of energy a sound wave carries per unit area.

Front

What causes sound to be produced?

Back

Sound is produced when a source of energy forces matter to vibrate.

Front

What is the relationship between frequency and pitch in sound?

Back

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

Front

What is amplitude in the context of sound waves?

Back

Amplitude refers to the maximum displacement of particles in a wave, which relates to the loudness of the sound.

Front

How does temperature affect the speed of sound?

Back

The speed of sound increases with an increase in temperature.

Front

What is the difference between longitudinal and transverse waves?

Back

In longitudinal waves, particles move parallel to the direction of wave propagation, while in transverse waves, particles move perpendicular to the direction of wave propagation.

Front

What is the unit of measurement for sound intensity?

Back

The unit of measurement for sound intensity is the decibel (dB).
