Speed of light 💡

[Yumi]

The Speed of Light Can Be Slowed Down: While the speed of light in a vacuum is about 299,792 kilometers per second (186,282 miles per second), it can be slowed down when passing through materials like water, glass, or diamond

Whoa, mind-blowing, right? It's crazy to think that something as fast as light can actually hit the brakes when it passes through certain materials like water or glass. Science never fails to amaze!
