An anode ray (also positive ray or canal ray) is a beam of positive ions that is created by certain types of gas-discharge tubes. They were first observed in Crookes tubes during experiments by the German scientist Eugen Goldstein, in 1886. Later work on anode rays by Wilhelm Wien and J. J.

Discovery of Anode Rays
The discovery of anode rays, also known as positive rays, is attributed to E. Goldstein in 1886. These rays are generated in a vacuum tube when a high voltage is applied, causing the gas inside to ionize and create positive ions that move towards the cathode.
What are Anode Rays?
- Anode rays are streams of positively charged ions.
- They are produced in a discharge tube when gas atoms are ionized and the resulting positive ions are attracted to the cathode.
Goldstein’s Experiment
- E. Goldstein conducted experiments using a modified cathode ray tube.
- He observed that when the cathode was perforated, rays emanated from the anode side, which he identified as positive ions.
- This was a significant discovery as it highlighted the presence of positively charged particles, complementing J.J. Thomson's work on cathode rays (which are negatively charged electrons).
Importance of Anode Rays
- The discovery of anode rays contributed to the understanding of atomic structure.
- It paved the way for further research in ionization, mass spectrometry, and the study of atomic particles.
Conclusion
In summary, the correct answer to the question of who discovered anode rays is c) E. Goldstein. His work laid the foundation for modern atomic physics and enhanced our understanding of matter at a fundamental level.
