Sound waves travel through the air as a series of compressions and rarefactions. The compressions are caused by the vibrating object pushing on the air molecules in front of it, and the rarefactions are caused by the object pulling on the air molecules behind it. The speed of sound waves depends on the temperature and density of the air.
What are the 5 key concepts shown in the thought experiment that will help you better understand sound waves and waves in general?
