Question

Explain how the cathode Ray was discovered?

Answer 1

The cathode ray was discovered through experiments by Sir William Crookes and J.J. Thomson. Crookes displayed the first cathode rays and found that they consist of charged particles. Thomson used a cathode ray tube to demonstrate that the rays were actually streams of electrons.

Step-by-step explanation:

The cathode ray was discovered through various experiments conducted by scientists. In 1878, Sir William Crookes displayed the first cathode rays using a modified Geissler apparatus. He found that the rays could be deflected by magnetic or electric fields, indicating that they consist of charged particles. Later, in 1897, J.J. Thomson used a cathode ray tube to demonstrate that the cathode rays were actually streams of negatively charged particles called electrons.

Answer 2

Cathode rays carry electronic currents through the tube. Electrons were firstdiscovered as the constituents ofcathode rays. J.J. Thomson used thecathode ray tube to determine that atoms had small negatively charged particles inside of them, which he called “electrons.”
