Who discovered canal rays (positive rays)?
Last Updated:

BJ.J. Thomson
CJames Chadwick
DErnest Rutherford
Correct Answer: Eugen GoldsteinYour Answer: A
Explanation
The correct answer is Option A — Eugen Goldstein. Eugen Goldstein, a German physicist, discovered canal rays (also called positive rays or anode rays) in 1886. These are positively charged rays that move towards the cathode in a gas discharge tube. Thomson discovered the ELECTRON (cathode rays) in 1897, NOT canal rays. Option C (James Chadwick): James Chadwick discovered the NEUTRON in 1932, NOT canal rays. Option D (Ernest Rutherford): Rutherford conducted gold foil experiment and proposed nuclear model of atom, but did NOT discover canal rays.
