Front

What type of wave does sound travel as?

Back

Sound travels as longitudinal waves.

Front

What does a high pitch sound indicate about its frequency?

Back

A high pitch sound has a high frequency.

Front

What characteristic does a very loud sound have?

Back

A very loud sound has a high amplitude.

Front

What characteristic does a very quiet sound have?

Back

A very quiet sound has a low amplitude.

Front

Which part of the ear increases the amplitude of sound waves entering the ear?

Back

The middle ear increases the amplitude of sound waves.

Front

What is the definition of sound?

Back

Sound is a type of energy made by vibrations that travels through air, water, or solids.

Front

What is frequency in relation to sound?

Back

Frequency is the number of vibrations or cycles per second of a sound wave, measured in Hertz (Hz).

Front

What is amplitude in relation to sound?

Back

Amplitude is the height of a sound wave, which determines the loudness of the sound.

Front

How does the medium affect sound travel?

Back

Sound travels faster in solids than in liquids, and faster in liquids than in gases.

Front

What is the relationship between frequency and pitch?

Back

Higher frequency corresponds to a higher pitch, while lower frequency corresponds to a lower pitch.
