Properties of Sound

Front

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

Back

The pitch of the sound wave increases (it has a higher pitch).

Front

What occurs to the pitch of a guitar string when it is tightened?

Back

The pitch gets higher as the string is tightened.

Front

What unit is used to measure the loudness of sound?

Back

Decibel (dB) is the unit used to measure loudness.

Front

What is the highest point on a sound wave called?

Back

The highest point on a wave is called the crest.

Front

What is the term for the lowest point on a sound wave?

Back

The lowest point on a wave is called the trough.

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.

Front

What is the unit of frequency in sound waves?

Back

Hertz (Hz) is the unit of frequency.

Front

How does the amplitude of a sound wave affect its loudness?

Back

Greater amplitude results in louder sounds, while smaller amplitude results in softer sounds.

Front

What is the term for the distance between two consecutive crests of a wave?

Back

The distance between two consecutive crests is called the wavelength.

Front

What happens to sound waves as they travel through different mediums?

Back

Sound waves travel at different speeds depending on the medium (faster in solids, slower in gases).
