State two differences between cathode & anode rays.

Explanation

(1) Cathode rays are composed of negatively charged particles whereas positively charged particles constitute anode rays.
(2) The ratio of charge and mass (e/m) of the constituent of cathode rays is always constannt and it does not depennd on the nature of the gas in the discharge tube and the cathode used. on the other hand, ratio of charge and mass (e/m) of the particle constituting the anode rays is not definite. it assume different values if different gases are used in the discharge tube.
