Answer:
Canal Rays were discovered by Eugen Goldstein
Explanation:
An anode ray is a positive-ion beam produced by some types of gas-discharge tubes. In 1886, German physicist Eugen Goldstein discovered them in Crookes tubes during tests. Wilhelm Wien and J. J. Thomson's further work on anode rays led to the invention of mass spectrometry.
When high voltage electricity is transmitted through a gas at very low pressure in a discharge tube, canal rays (or anode rays) are streams of positively charged particles that flow towards the negative electrode (cathode).
