Question

How will you prove that cathode rays are made up of material particles?

Answer 1

Definition

Cathode rays are the beam of electrons emitted from the cathode of a discharge tube containing gas at very low pressure by passing electricity of high voltage through it.

Cathode rays consist of matter particles and possess energy: In the presence of an electrical or magnetic field, the behavior of cathode rays is similar to that of negatively charged particles, suggesting that the cathode rays consist of negatively charged particles, known as electrons.
