Sound wave
1 answer
A sound wave is a type of wave that carries sound through a medium, such as air or water. Sound waves are created by the vibration of an object and travel through the medium in a series of compressions and rarefactions. These waves can be heard by human ears and are essential for communication and experiencing the world around us. Sound waves are characterized by their frequency, amplitude, and wavelength, which determine the pitch, volume, and timbre of the sound.
