Question on: SS1 Physics - Sound And Waves

Sound waves are mechanical waves that require a medium, such as air, water, or solids, to propagate. They are produced by vibrating objects, which create compressions and rarefactions in the medium. In a sound wave, the compressions are regions of high pressure, while rarefactions are regions of low pressure. The wave travels as these pressure variations propagate through the medium in a longitudinal fashion.
