Discovery of Anode Rays
- The discovery of anode rays is credited to the German scientist Eugen Goldstein in the late 19th century.
- Goldstein observed a glow in a cathode ray tube when a perforated anode was introduced.
- He called these rays "Kanalstrahlen" or canal rays.
- Goldstein's experiments were a continuation of the earlier work done by J.J. Thomson on cathode rays.
- Cathode rays are streams of electrons that are emitted from the cathode in a vacuum tube.
- Goldstein's experiments with cathode rays led him to discover that there were also positively charged rays moving in the opposite direction, which he called anode rays.
- Anode rays are formed when residual gas molecules in the cathode ray tube are ionized by the high-speed electrons from the cathode.
- These positively charged ions are attracted to the negatively charged anode, creating a glow or fluorescence.
- Goldstein's discovery of anode rays provided further evidence for the existence of charged particles and contributed to the development of the understanding of atomic structure and the nature of electricity.
Therefore, the correct answer is B: Goldstein.
