Question
Explain the characteristics of canal rays (positively charged particles).
✓

Answer

Following are the characteristics of canal rays :
(i) Positively charged particles depend on the nature of the gas present in the cathode ray tube and they are simple positively charged gaseous ions.
(ii) The ratio of charge and mass of the particles depends on gas from which they are produced.
(iii) The electric charge of some positively charged particles is a simple multiple of fundamental unit.
(iv) The behavior of these particles in magnetic and electric fields is opposite to the behaviour of electron or cathode ray.
(v) The mass of each particle of positive rays is approximately equal to the atomic weight of the gas used in the discharge tube.
