(i)Cathode waves always travel in straight path.

(ii) Cathode rays exert mechanical force on the objects they strike.

(iii) Cathode rays make fluorescence.

(iv) When cathode rays strike a solid body, specially a metal of higher atomic weight and high melting point X-rays are emitted from the objects.

(v)  Cathode rays ionize the gases by which they are passed.

(vi) Cathode rays can penetrate by thin foils of metal.

(vii) Cathode rays are establish to have velocity ranging1/30 th   to 1/10 th  of velocity of light.
