Sound Waves

Front

What happens to the pitch of a sound wave as the frequency decreases?

Back

The pitch becomes lower.

Front

Sound waves must travel through what?

Back

A medium.

Front

Which sound wave has high frequency?

Back

Sound wave 4.

Front

Where can sound waves NOT travel?

Back

Space.

Front

What happens to the loudness of a sound as the amplitude increases?

Back

The loudness increases.

Front

Define sound wave.

Back

A sound wave is a vibration that travels through a medium (like air, water, or solids) and can be heard when it reaches a person's or animal's ear.

Front

What is frequency in relation to sound waves?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz). Higher frequency means a higher pitch.

Front

What is amplitude in sound waves?

Back

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

Front

What is the relationship between frequency and pitch?

Back

As frequency increases, the pitch of the sound becomes higher.

Front

What is a medium in the context of sound waves?

Back

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