User: what are cathode rays?

Weegy: Cathode rays are electrons which are emitted from gases trapped inside a cathode ray tube. A cathode ray tube is a glass tube from which most of the air has been evacuated. [ The tube has electrodes placed at each end and a high-voltage current is passed through the electrodes. A ray is produced at the cathode (negative pole) and travels to the anode (positive pole). The ray is called "cathode ray" because it comes from the cathode. JJ Thomson used cathode ray tubes to demonstrate that the cathode ray responds to both magnetic and electric fields. Since the ray was attracted to a positive electric plate placed over the cathode ray tube (beam deflected toward the positive plate) he determined that the ray must be composed of negatively charged particles. He called these negative particles "electrons."
