Why Is the Water Blue in a Nuclear Reactor?
Hey everyone! Have you ever wondered why the water in a nuclear reactor glows blue? Let's dive into the science behind this fascinating phenomenon.
First, let's talk about the speed of light. In a vacuum, light travels at about 300,000 kilometres per second. But when light moves through water, it slows down to around 225,000 kilometres per second.
In a nuclear reactor, high-energy electrons are released during nuclear reactions. These electrons can travel faster than the speed of light in water.
When these charged particles zoom through the water faster than light, they emit Cherenkov radiation. It's like a sonic boom, but with light instead of sound.
Cherenkov radiation gives off a continuous spectrum of light, peaking in the ultraviolet range. However, due to how our eyes perceive light and how water absorbs it, we see this radiation as a beautiful blue glow.
So, the next time you see that eerie blue glow in a nuclear reactor, you'll know it's because of particles moving faster than light in water, creating Cherenkov radiation.
