Eugene Goldstein
Eugen Goldstein proposed the expression cathode rays(but he was not the discoverer) and discovered the so-called in the era canal rays.
Canal rays, sometimes called anode rays, were first observed in by Eugen Goldstein in 1886. These rays are streams of positive ions in a rarefied gas and have a higher mass compared to electrons.
There are no rays assign as Anode rays canal rays is another name for positive rays in a discharge tube, The X-rays are emitted from anode plate.
canal rays
Anode Rays are called the canal rays as the cathode used is perforated and the anode rays pass through the holes or canals of The cathode opposite to the anode.
Johann Wilhelm Ritter discovered ultraviolet rays
it opened in 1914.The Panama canal was not discovered. To be discovered it has to all ready exist. It was built by the United States.
Cathode rays were discovered by JJ Thomson and carry a negative charge Anode rays were discovered by Goldstein and carry a positive charge.
protons
No one found it. Panama Canal was built
Cosmic rays were discovered by Victor Hess in 1912.
