Mini-Quiz: Overview of Sound Waves

by Ron Kurtus (revised 1 December 2009)

Take this Mini-Quiz to check your understanding of the lesson material.



1. Why doesn't sound travel through a vacuum?

Sound is a waveform in matter, and there is no matter in a vacuum

Vacuums absorb most of the sound

It does travel in space, as verified on Star Trek

2. How is a sound wave different than a water wave?

Sound does not travel through water

Water waves have a wavelength, while sound waves don't

A water wave is a transverse wave, while sound is a compression wave

3. What happens when sound hits a thin membrane?

It causes the membrane to vibrate

The membrane reflects most of the sound

The amplitude of the sound increases

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.
