Introduction thomson started the cathode ray experiment in the 1894 (19th century) at the cavendish laboratory at cambridge university he experimented. Jj thompson did an experiment using a cathode ray tube and found that electrons passed from the surface of the cathode and accelerate toward the positively charged anode.

Topic 7 | the cathode-ray tube let’s look at how the concept of potential is applied to an important class of devices called cathode-ray tubes,or “crts” for short cathode-ray tube. The cathode ray tube (crt) is a vacuum tube that contains one or more electron guns and a phosphorescent screen, and is used to display images it modulates.
A summary of the cathode ray
There were a number of results gathered over the years by cathode ray tube researchers 1) if an object is placed in the path of the cathode ray, a shadow of the object is cast on the.
