What is the
speed of beta particles in a vacuum?
The speed of beta particles is less than that the
speed of gamma particles but greater than the that of alpha particles, the
gamma has a speed same as that of a light in a vacuum,
Light travel
in a vacuum at a speed of three hundred thousand kilometers per second. 300
million m/s or 3X108m/s in a vacuum.
The speed of gamma ray in a vacuum is 0.995c,
where c is the speed of light.
Because of
the high speed of beta particles, they can penetrate thin object like papers etc.
Beta particles are can ionize air, they can be deflected by both electrical and
magnetic field,
