Question

what is the difference between cathode and anode rays

Answer 1

• cathod rays are a stream of negatively charged particles. These rays were produced when Sir J J Thomson conducted an experiment in a discharge tube in which air at less pressure and high voltage is used. the pressure of gas is usually made 0.01 to 0.001 mm of Hg and current of 10000 volts is applied to make it a good conductor of electricity. The particles constituting these rays are known as electrons.

The characteristics properties of cathode rays are.
1 These rays consists of negatuively charged particles.
2. these rays are a stream of fast moving particles.
3. They possess kinetic energy.
4 these can penetrate through matter.
5 their e/m ratio is constant
6 They produced floroscence on soda lime glass.

• Anode rays are a stream of positively charged particles. These were discovered by E. Goldstein when he used a perforated cathode in the disharge tube. The constituent particles of these rays are known as protons . Their characteristics properties are

1 they are fast moving positively charged particles.
2 their e/m changes. It depends on the nature of gas used.
3 the also possess kinetic energy.
