Cherenkov Radiation : Particles Faster Than the Speed of Light?

The video explains how light travels at different speeds in various mediums, such as a vacuum and water. In water, light travels slower, allowing particles like electrons to exceed its speed, creating Cherenkov radiation, a blue glow. This phenomenon is similar to a sonic boom but with light. It occurs in nuclear reactors and can be observed in places like the Sudbury Neutrino Observatory. The video concludes by thanking patrons and encouraging support.
