Which of the following statements are correct about the cathode ray experiment?
(a) The cathode rays starts from anode and move towards cathode.
(b) Television picture tubes are cathode ray tubes and pictures result due to fluorescence on the television screen coated with certain fluorescent materials.
(c) In the presence of magnetic or electric field, the behaviour of cathode rays are similar to negatively charged particles.
(d) The characteristics of cathode rays does not depend upon the material of electrodes but nature of gas present in the cathode ray tube.
