(iv) Cathode rays consist of negatively charged particles. (iii) These rays themselves are not visible but their behaviour can be observed with the help of certain kind of materials (fluorescent or phosphorescent) which glow when hit by them. (ii) Cathode rays start from cathode and move towards the anode. (i) Cathode rays travel in straight line. These were called cathode rays or cathode ray particles. When sufficiently high voltage is applied across the electrodes, current starts flowing through a stream of particles moving in the tube from the negative electrode (cathode) to the positive electrode (anode).
The pressure of different gases could be adjusted by evacuation. The electrical discharge through the gases could be observed only at very low pressures and at very high voltages. It is sealed at both the ends and fitted with two metal electrodes as shown in Fig. He performed the experiment in a discharge tube which is a cylindrical hard glass tube about 60 cm in length. In 1879, William Crooks studied the conduction of electricity through gases at low pressure.
