How does sound travel? – What happens next?

The video explains how sound travels through vibrating air particles. It demonstrates this by placing a clock in a capsule and removing the air to create a vacuum. Without air particles, sound cannot travel, and the alarm becomes inaudible. This illustrates the necessity of a medium for sound transmission.

What is the role of air particles in sound transmission?

Describe the process of creating a vacuum around the clock.

What occurs when air is removed from the capsule?

Why can we no longer hear the alarm in a vacuum?

What happens to sound when there are no air particles?
