Front

What is amplitude?

Back

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

Front

How does sound travel through different states of matter?

Back

Sound travels fastest through solids, slower through liquids, and slowest through gases.

Front

What is the relationship between sound waves and vibrations?

Back

Sound waves are created by the vibrations of objects, which cause the surrounding medium to vibrate as well.
