Example Formula

The formula for calculating the Cherenkov cone angle (θ) is:

cos(θ) = c / v


  1. θ: Cherenkov cone angle (in radians)
  2. c: Speed of light in vacuum (approximately 3 x 108 m/s)
  3. v: Velocity of the charged particle in the medium (in m/s)

Who Wrote/Refined the Formula

The formula for the Cherenkov cone angle is derived from the fundamental principles of special relativity and electromagnetic theory. It is a result of the work of multiple physicists, including Pavel Alekseyevich Cherenkov, who discovered and explained the phenomenon of Cherenkov radiation in 1934. The formula has been refined and studied by numerous researchers in the field of particle physics.
