Explanation:
Energy can be defined as the ability (capacity) to do work. The various forms of energy are solar energy, electrical energy, chemical energy, thermal energy, wind energy, nuclear energy, sound energy, etc.
Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.
Sound travels faster through solids than it does through either liquids or gases due to the faster vibration of its particles.
Hence, mechanical waves are created when a source of energy causes a medium to vibrate.
