Exploring the Science of Sound: Speed and Mediums

The video explains why we see fireworks before hearing them, due to the speed difference between light and sound. It introduces the bell jar experiment to demonstrate how sound travels through different media: air, water, and solids. The experiment shows that sound requires a medium to travel and cannot move through a vacuum. Sound travels fastest in solids due to tightly packed particles, followed by water, and slowest in air.

What factors affect the speed of sound in different media?

Why can't sound travel through a vacuum?

How does sound travel in solids compared to air?
