Question

what is cathode rays? Give proper definition?

Answer 1

 A cathode ray is a beam of electrons in a vacuum tube traveling from the negatively charged electrode (cathode) at one end to the positively charged electrode (anode) at the other, across a voltage difference between the electrodes. ... Since electrons are repelled by the negative ...

Answer 2

Cathode rays are so named because they are emitted by the negative electrode, or cathode, in a vacuum tube. To release electrons into the tube, they first must be detached from the atoms of the cathode. ... The voltage applied between the electrodes accelerates these low mass particles to high velocities.

Definition of cathode ray. 1 cathode rays plural : the high-speed electrons emitted in a stream from the heatedcathode of a vacuum tube. 2 : a stream of electrons emitted from the cathodeof a vacuum tube —usually used in plural.
