OP: Is electron able to move faster than light?
There is no material particle that can travel faster than the speed at which light passes through vaccum.
We know that light travels faster in a medium than it does in vaccum. Refractive index n is a measurement of how light travels through a medium relative to air (vaccum).
n = (speed light in vacuum)/speed light in the medium.
For example, the water’s refractive index is 1.33 in comparison to air. The speed of light in water is therefore 2.25x108m/s. This speed is not the speed of electrons. Only electrons can travel faster than the speed of light in a medium. The medium cannot contain heavier particles that can move at the speed of light.
This phenomenon causes the emission of visible radiation known as Cerenkov Radiation. A light water reactor is filled with a bluish glow. A light water reactor can be opened. This reactor is located at Kumatori-Cho in Sennan-Gun (Osaka, Japan), where I was able to do some research. When the reactor was operating, one could see the bluish glow filling the reactor rods.
Yes, the speed of light can be exceeded by energetic electrons within a material medium. This causes visible radiation to occur in the bluish portion of the electromagnetic spectrum. Radiation is useful in the detection of radiations. It also has many desirable features that make it an important tool for high-energy physics.
