Study Notes
Sound Waves
- A sound wave is a mechanical or longitudinal wave caused by vibrations of bodies.
- Sound waves require a medium to travel through.
- In a vacuum, no sound can be made because there are no particles to vibrate.
- In a longitudinal wave, particles of the medium vibrate in the same direction as the wave travels.
- Sound waves consist of compressions and rarefactions, formed as particles compress together and then spread out.
- Sound waves travel in all directions away from their source.
This quiz explores the basics of sound waves, including their causes, properties, and behavior in different mediums. Learn about compressions, rarefactions, and more!
