The Wonders of Sound Waves

Sound waves are vibrations that travel through a medium, like air or water. Sound can be heard when these waves reach a person's ear. Frequency determines the pitch of a sound, while amplitude determines its volume.

Concepts:

frequency: The number of times per second that a wave repeats itself. amplitude: The height or depth of a wave, which corresponds to its volume. medium: A substance through which a sound wave can travel, such as air or water.

Fun facts:

Humans can only hear sound waves between 20 Hertz and 20 000 Hertz. Sound travels faster in air than it does in water. The loudest sound ever recorded was a rocket launch in 1970 and it was 180 dB!
