Accepted Answer

A guitar makes sound when you pluck its strings. The strings vibrate and produce sound waves.

Question 13

We can't see sound waves with our eyes, but we can sometimes see things vibrate, like a speaker. Special machines can show us what sound waves look like.

Accepted Answer

High sounds come from fast vibrations, like a bird chirping. Low sounds come from slow vibrations, like a big drum.

Question 17

Why does sound travel faster in water than in air?

Accepted Answer

Water molecules are closer together than air molecules, so the waves move faster. It's like how it's easier to pass a message down a line of people standing close.
