Sound Waves

Front

What is the relationship between frequency and pitch in sound waves?

Back

High frequency sounds have a high pitch.

Front

What occurs during a rarefaction in a sound wave?

Back

Particles move apart.

Front

What is generated when particles in a medium move close together?

Back

A compression.

Front

How does the amplitude of a wave relate to its energy?

Back

The amplitude of a wave increases with increased energy.

Front

In which medium does sound travel fastest: solid, liquid, or gas?

Back

Sound travels fastest in solids.

Front

Define sound wave.

Back

A sound wave is a longitudinal wave that is created by vibrating objects and propagates through a medium.

Front

What is the difference between compression and rarefaction in sound waves?

Back

Compression is when particles are close together, while rarefaction is when particles are spread apart.

Front

What is the unit of frequency?

Back

Hertz (Hz).

Front

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

Back

Approximately 343 meters per second.

Front

How does temperature affect the speed of sound in a medium?

Back

The speed of sound increases with an increase in temperature.
