Cathode Ray

Real World Example

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.
