(i) The anode rays originate in the region between
two electrodes in the discharge tube.
(ii) These rays are made of material particles.
(iii) These rays are positively charged.
(iv) The magnitude of charge on anode-rays varies
from particle to particle depending on the number of electrons lost by an atom or molecule.
(v) The mass of positive particles which constitute
these rays depend upon the nature of gas in the tube.
(vi) The charge/mass (e/m) ratio of anode-rays is not
constant but depends upon the nature of gas in the tube.
