Question

study of cathode ray​

Answer 1

Explanation:

Thomson showed that cathode rays were composed of a previously unknown negatively charged particle, which was later named the electron. Cathode ray tubes (CRTs) use a focused beam of electrons deflected by electric or magnetic fields to render an image on a screen.....

Hope it helps you ☺️

Answer 2

Answer:

Explanation:

The stream of electrons in cathode ray tube constitutes the cathode rays. Electrons are emitted by hot filament by the process of thermionic emission. These electrons pass through controlling and focusing device . They are accelerated by applying appropriate voltage between cathode and anode and finally made incident on a flourascent screen after passing through cross electric and magnetic fields.
