How does sound travel in air?
Advertisements
उत्तर
Sound travels in air as a longitudinal wave through the vibration of air molecules. When a sound source vibrates, it creates compressions (high pressure) and rarefactions (low pressure) that propagate through the air. These pressure variations transfer sound energy from one molecule to another, allowing the wave to travel. The sound reaches our ears, causing the eardrum to vibrate, which is then processed by the brain as sound. Since sound needs a medium, it cannot travel in a vacuum.
