Properties of Sound Waves

Front

What happens to the sound when the amplitude of a sound wave is increased?

Back

The sound gets louder.

Front

What happens to the pitch of a sound when the wavelength of a sound wave is decreased?

Back

The pitch becomes higher.

Front

What is the term for the number of waves that occur in a time interval?

Back

Frequency.

Front

Which wave has a greater frequency: Wave A or Wave B?

Back

Wave A.

Front

What do sound waves cause air molecules to do as they travel through air?

Back

Vibrate.

Front

What is amplitude in the context of sound waves?

Back

Amplitude is the maximum extent of a vibration or oscillation, measured from the position of equilibrium.

Front

How does frequency affect the pitch of a sound?

Back

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

Front

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

Back

As wavelength decreases, frequency increases, and vice versa.

Front

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

Back

Approximately 343 meters per second.

Front

What is a compression in a sound wave?

Back

A compression is a region in a sound wave where the particles are closest together.
