Waves and Sound Sound as a form of energy, requires a medium (solid, liquid, or gas) doesn’t travel in vacuum. transferring the disturbance through the medium in the form of a wave. There are two types of waves: Longitudinal waves: Particles oscillate parallel to wave direction (e.g., sound waves). Sound waves are mechanical longitudinal waves. Sound travels […]
