CathodeRays Are Composed of What Fundamental Particle
Cathode rays are streams of electrically charged particles that emerge from the negative electrode (cathode) in a vacuum tube when a high voltage is applied. Because of that, The fundamental particle that constitutes cathode rays is the electron, a subatomic particle with a negative electric charge, negligible mass compared to atomic nuclei, and a well‑defined charge‑to‑mass ratio (e/m). This article explains the historical discovery, the experimental steps that revealed the nature of cathode rays, the scientific reasoning behind identifying them as electrons, and answers common questions about this foundational concept in physics It's one of those things that adds up. Took long enough..
Introduction
The phrase “cathode rays” immediately evokes images of glowing beams inside glass tubes, yet the true essence of these rays are composed of what fundamental particle
