Unit 6 Practice Assessment

Front

What is pitch?

Back

Pitch is how high or low a sound is, which depends on the frequency of the sound wave. Higher frequency means higher pitch.

Front

What does a sound wave model represent?

Back

A sound wave model visually represents how sound travels through a medium in waves.

Front

What is the form of sound?

Back

Sound is a form of energy.

Front

How does sound travel?

Back

Sound travels in the form of waves.

Front

Why does sound need a medium to travel?

Back

Sound needs a medium because the molecules must vibrate back and forth; without matter, nothing can vibrate to create sound.

Front

What is frequency?

Back

Frequency is the number of waves that pass a point in a given amount of time, affecting the pitch of the sound.

Front

What is a medium in the context of sound?

Back

A medium is a substance (solid, liquid, or gas) through which sound waves travel.

Front

What happens to sound in a vacuum?

Back

In a vacuum, sound cannot travel because there are no molecules to vibrate.

Front

What is the relationship between frequency and pitch?

Back

The relationship is direct: as frequency increases, pitch increases.

Front

Can sound travel through water?

Back

Yes, sound can travel through water, which is a medium that allows sound waves to propagate.
