1 Answer

Answer :

Characteristics of Alpha Rays :
(1) Composition :
They are comprised of positively charged particles.
(2) Speed :
Their speed is about 1/10 th of the speed of light.
(3) Penetration :
They cannot pass through a thick metal foil because of their heavy mass.
(4) Deflection :
They are deflected towards the negative pole.
(5) Ionization :
They can ionize air or gas.

Characteristics of Beta Rays :
(1) Composition :
They are comprised of negatively charged particles.
(2) Speed :
They travel with the speed of light.
(3) Penetration :
They could pass through a few millimeters thick metal sheet because of more penetrating power.
(4) Deflection :
They are deflected towards the positive pole.
(5) Ionization :
They can ionize air or gas.

Characteristics of Gamma Rays :
(1) Composition :
They are comprised of neutral particles.
(2) Speed :
They travel with the speed of light.
(3) Penetration :
They possesses the highest penetrating power as compare to alpha or beta rays.
(4) Deflection :
They do not deflect in any electric field. Hence they carry no charge.
(5) Ionization :
