The Physics of Waves. … WebA wave that moves in the direction perpendicular to its propagation. A sound wave is an example of a longitudinal wave. Water waves are an example of a transverse wave. It is made of refractions and compressions. It is made of troughs and crests. This wave can be produced in any medium such as gas, liquid or solid.
WebDec 28, 2024 · Sound is a type of mechanical wave or an oscillation of matter. When a sound wave propagates through a medium, such as air, it does so by causing the air molecules to vibrate, which causes changes in air pressure. The speed of sound in air is around 343 m/s but can vary with temperature.
