When high velocity particles travel faster than the speed of light in a medium they create a blue flash. This is called Cerenkov Radiation, why does this happen and why is it blue?

If you want us to answer the question, it happens because the particle is decelerating, and the blue light you see is the light emitted from the energy lost in this process.
