Cathode rays are streams of negatively charged particles, known as electrons, that are emitted from the cathode (negative electrode) of a device when an electric current is passed through it. The electrons are accelerated by an electric field, creating a beam of particles that can be manipulated and directed. This fundamental principle has led to the development of various devices, including cathode ray tubes (CRTs) and electron microscopes.
