BJS -2023 Sound waves are mechanical waves that require a medium to travel. Their speed depends on the properties of the medium, particularly its elasticity (stiffness) and density. Sound travels fastest in solids because their particles are closely packed and interactions between them are strong, allowing vibrations to propagate quickly. Sound travels slower in liquids and slowest in gases due to the weaker interactions and greater distances between particles. Sound cannot travel through a vacuum.
