4. Sound (right)
Sound is produced when molecules push against each other causing vibrations. We hear sound b/c sound waves vibrate on the eardrum.
2) Sound moves as a longitudinal wave- needs a medium (air, water etc)
Speed of sound depends on spacing of molecules. Sound moves faster in water compared to air as the molecules in water are closer together in a liquid.
What is sound?
2) How does sound travel?
