what are sound waves?
1 answer
Sound waves are mechanical waves that propagate through a medium, such as air, water, or solids. They are created when an object vibrates, causing the particles in the medium to vibrate and transfer the energy of the vibration from one particle to the next. These vibrations travel in the form of waves, moving in a back-and-forth motion, and can be detected by our ears as sound. Sound waves can vary in frequency and amplitude, which determines the pitch and volume of the sound we perceive.
