Question

What are cathod rays????​

Answer 1

This is your answer dear I wish this may help you

Explanation:

Cathode rays are streams of electrons observed in discharge tubes. If an evacuated glass tube is equipped with two electrodes and a voltage is applied, glass behind the positive electrode is observed to glow, due to electrons emitted from the cathode

Answer 2

Cathode rays are electron beams observed in a vacuum tube.

• The cathode terminal in a cell means that it is a negative terminal, and thus it is named so because it is emitted from the negative side.
• They are the basic beams of electrons that can be only observed in vacuum tubes.
• When the voltage is applied, then only the beams can be seen perfectly as coloured gases.
• It is obvious that the electrons must be detached or separated from their atom to exert in a vacuum tube.
