Cathode Ray:
Imagine trying to get a crowd of people to move quickly through a narrow hallway to reach an exit. This is similar to the way a cathode ray works, where electrons are funneled from the negative electrode, like the crowd, through a narrow tube. In this analogy, the people represent electrons, the narrow hallway is the cathode ray tube, and the exit they are heading towards is the positive electrode, effectively demonstrating how directed movement occurs in both scenarios.
Practice Version
Cathode Ray: A stream of electrons produced at the negative electrode of a cathode ray tube. Cathode ray. A cathode ray is a beam of electrons traveling through a vacuum in a cathode ray tube.
