Which of the following media allow the transmission of sound waves through them? I. Air II. Liquids III. Solids
Explanation
Sound is a mechanical wave. It travels by making particles of a medium vibrate, so it needs particles to pass on the vibration.
Air, liquids and solids all contain particles, so sound travels through all three. It actually travels fastest in solids and slowest in air, because particles in solids are closer together.
Sound cannot travel through a vacuum, where there are no particles.
