Question

Quizplus · Accepted Answer

When a tuning fork is struck, it vibrates and causes the air around it to also vibrate. This vibration of air consists of compressions (areas of high pressure) and rarefactions (areas of low pressure), which travel as sound waves to the ear, allowing the sound to be heard.
