cherenkov radiation?
In: Physics
Think of a particle of radiation like a jetski with two passengers. The jetski is buzzing along as fast as it can on a lake and everything’s fine. But then it moves from the lake to another medium – dry land – where it can’t go as fast. The moment it hits the dry land it’s forced to go slower, and as a result it releases some of the energy, in the form of the passenger. Your girlfriend flying off the jetski when it hits dry land is like the particle of radiation releasing a photon when it moves from water to the air.
