Sound Waves

Front

What are sound waves?

Back

Sound waves are vibrations that travel through air, water, or solid materials, allowing us to hear sounds.

Front

Can sound waves travel through outer space?

Back

No, sound waves cannot travel through outer space because there is no medium (like air or water) for them to move through.

Front

What determines the pitch of a sound?

Back

The pitch of a sound is determined by its frequency, which is the number of vibrations per second.

Front

What is frequency?

Back

Frequency is the number of times a sound wave vibrates in one second, measured in Hertz (Hz).

Front

What happens to the pitch when the frequency increases?

Back

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

Front

What is sound energy?

Back

Sound energy is a form of energy produced by vibrating objects, which creates sound waves.

Front

What is an echo?

Back

An echo is a sound that is reflected off a surface and heard again after a short delay.

Front

What is amplitude in relation to sound?

Back

Amplitude refers to the height of the sound wave, which determines the loudness of the sound.

Front

What is the relationship between amplitude and volume?

Back

Higher amplitude means a louder sound, while lower amplitude means a softer sound.

Front

What is a medium in the context of sound waves?

Back

A medium is a substance (like air, water, or solid materials) through which sound waves travel.
