Explain Cathode Ray Experiment :-​

Answer 1

$\huge\boxed{\fcolorbox{black}{grey}{Hi mate!}}$

In 1897, British physicist J. J. 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.

Answer 2

• Cathode ray experiment was a result of english physicists J J Thomson who was experimenting with cathode ray tubes. For this experiment, he takes a tube made glass which contains two pieces of metals at the opposite ends which acted as an electrode. And these two metal pieces were connected with an external storage.

•The procedure the experiment are:-

1. High Voltage is passed to the two metal pieces to ionise the air.

2. Make it a conductor of electricity

3. As the circuit was completed, the electricity starts to flow

4. The ray produced by applying a high voltage to the tube.

5. The positive and negative pole kept on one side of the discharge ray.

6. When the dipoles were applied, the ray repelled by the negative pole and it deflected towards the positive pole.

7. and finally it was noted that the deflection was towards the side that's why Constituents of the discharge tube we're negatively charged.
