Question

How cathode rays were produced?​

Answer 1

Answer:

Cathode rays come from the cathode, because the cathode is charged negatively. So those rays strike and ionize the gas sample inside the container. The electrons that were ejected from gas ionization travel to the anode. These rays are electrons that are actually produced from the gas ionization inside the tube.

Answer 2

When a high voltage is applied between the cathode and the anode, the electrons are accelerated at high speed from the cathode to the anode. This stream of electrons which is moving at high speed is called cathode rays.
