Thomson found that the cathode rays were actually streams of with the following properties: ________
a) they traveled in straight lines, they were the composition of the material from which they originated, and they carried a negative electrical charge.
b) He measured the charge-to-mass ratio of the particles and found that the cathode ray particle was about 2000 times lighter than hydrogen.

The cathode rays are also known as electrons. They are a stream of negatively charged particles.

What are cathode rays?

The term cathode rays were used by JJ Thompson to describe a stream of rays that emanate from the cathode in a cathode ray tube. These rays correspond to what we know today as electrons.

The cathode rays;

  • Travelled in straight lines
  • Depended on the nature of gas in the tube
  • Were deflected by electric and magnetic fields
  • Produced mechanical motion in objects on their path.

Electron beams such as cathode rays travel in a straight line.

What are Cathode rays?

Cathode rays are electrons that are observed in vacuum tubes, is streams of electrons are emitted by the negative electrode.

  • Cathode rays travel in straight lines and usually cast sharp shadows.
  • Cathode rays are negatively charged electrode
  • Cathode rays are usually deflected by an electric and magnetic field.

Therefore, cathode rays traveled in straight lines, they were the composition of the material from which they originated, and they carried a negative electrical charge.
