Sound

What are you doing when you're making sound?

• Causing photons to travel.

• Causing air molecules to vibrate.

• Causing electromagnetic waves to radiate.

• Causing air pressure to drop.

What is compression?

• When air molecules move apart from one another.

• When air molecules collide with one another.

• When air molecules become packed tightly together.

• When air molecules move around freely.

What would a wave with a low amplitude sound like?

• It would sound quiet.
