Sound waves are mechanical waves, meaning they require a material medium (solid, liquid, or gas) through which to travel. They cause vibrations in the particles of the medium, and these vibrations are transmitted from one particle to the next. In a vacuum, there are essentially no particles to vibrate, so sound cannot travel through it.<br \/>\n<\/section>\n<section id=\"pyq-key-points\">\nSound waves are mechanical waves and require a medium (solid, liquid, or gas) to propagate.<br \/>\n<\/section>\n<section id=\"pyq-additional-information\">\nSound waves in fluids (like air and water) are primarily longitudinal. Sound can propagate through various media, including water (as demonstrated by underwater sound) and solids like steel. The speed of sound varies depending on the medium; it is generally fastest in solids (due to stronger inter-particle forces), slower in liquids, and slowest in gases. The speed of sound in steel is significantly higher than its speed in air.<br \/>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Which one of the following statements is NOT true about the sound waves?
