How does the sound produced by a vibrating object in a medium reach your ear?

1. Through electron transfer
2. Through the vibration of particles
3. Sound waves don't need a medium
4. Not enough data

Correct answer: Through the vibration of particles

Solution

Sound travels through a medium by making its particles vibrate and pass the disturbance along from one particle to the next. That is why sound cannot travel in a vacuum and why the correct choice is the vibration of particles.
