Question

It is said that cathode ray particles, when pass through metal, produce heating effect.

But how? Please tell me the full process.

Answer 1

Cathode rays are accelerated electrons. They have high kinetic energy. When they fall on a matter, they lose a part of their energy as a friction energy which is responsible of heating the matter.

This cause vibration in molecules

forms of interactions that might take place, simultaneously with the friction, between the cathodic rays and the matter.
