Answer 1

Sir JJ Thomson and others found that cathode rays have the following characteristics.

1. they originate at that cathode and travel in straight lines .
2. cathode rays are a stream of particles
3. the particles constituting cathode rays and negatively charged
4. the particles constituting cathode rays are all a like they do not change with the cast the electrodes and the kind of class used for making the tube.

Answer 2

Explanation:

Some properties of cathode rays:

They travel linearly.

They have a negative electric charge.

They have particle property.

Magnets can deflect them.

Charge/mass ratio of the rays is constant.

They travel from the cathode to the anode.

Their properties are independent from the electrodes and gas present in the cathode ray tube.

Cathode ray, stream of electrons leaving the negative electrode (cathode) in a discharge tube containing a gas at low pressure, or electrons emitted by a heated filament in certain electron tubes. Cathode rays focused on a hard target (anticathode) produce X-rays or focused on a small object in a vacuum generate very high temperatures (cathode-ray furnace). When cathode rays strike certain molecules used to coat a cathode screen, they cause the molecules (and hence the screen) to emit light. This effect, when coupled with the controlled deflection of a cathode ray by electric or magnetic fields, gives rise to the cathode-ray oscilloscope (cathode-ray tube [CRT]) for monitoring variations and values of an alternating voltage or current and to the picture tube of television and radar.
