Unit 2: Sound Waves Part 1

Front

What happens to the wavelength of a sound wave if its frequency increases?

Back

The wavelength decreases.

Front

Which wave characteristic is responsible for the loudness of a sound?

Back

Amplitude.

Front

What does a wave with greater intensity produce?

Back

A louder sound.

Front

What does the pitch of a sound depend on?

Back

Frequency.

Front

What are spread out areas or areas of decreased pressure on a sound wave known as?

Back

Rarefaction.

Front

What is the term for the distance between two consecutive compressions in a sound wave?

Back

Wavelength.

Front

What is the unit of frequency?

Back

Hertz (Hz).

Front

What is the relationship between frequency and pitch?

Back

Higher frequency results in a higher pitch.

Front

What is the term for areas of increased pressure in a sound wave?

Back

Compression.

Front

How does amplitude affect sound?

Back

Greater amplitude results in louder sound.
