# Cherenkov Radiation Cone Angle Calculator

Cherenkov radiation is defined as an electromagnetic radiation emitted when a charged particle passes through a dielectric medium at a speed greater than the phase velocity of light in that medium. It is also known as Vavilov–Cherenkov radiation. This online Cherenkov radiation cone angle calculator helps you in calculating the cone angle resulted from Cherenkov radiation.

### Example:

Calculate Cherenkvow radiation cone angles given that, speed of light = 299792458 m/s, refractive index = 28945156 and particle velocity = 5 m/s.

#### Solution:

Cherenkov Radiation Cone Angle = sin^{-1}(299792458 / 28945156 x 5)

= 0.0362 degrees.
