THIS is what happens when matter goes faster than light speed. It’s not just some blue light. You’re watching Cherenkov Radiation take place. In water, light travels slower, and when charged particles move faster, they leave behind this cool blue echo of light. 💡 For more cool science like this, catch up on episodes of @okaytobesmart on YouTube! | PBS Digital Studios

Nuclear reactor startup ☢️ The blue glow is a classic example of Cherenkov radiation, which occurs when a charged particle passes through a dielectric medium at a speed greater than the phase velocity of light in that medium. Follow @betaeq | Beta EQ

The Cherenkov effect, also known as Cherenkov radiation, is the emission of light when a charged particle travels through a dielectric medium at a speed greater than the speed of light in that medium. This phenomenon is analogous to a sonic boom, where a shockwave of sound is produced when an object surpasses the speed of sound. Follow @thatisnewton ,All credits to respective creators/owners.
