It is also identical with the cathode ray of the vacuum tube.
The beta particles emanating from radium were soon identified with the electrons of the cathode ray.
The cathode ray, when properly used, will bombard the atoms and knock electrons loose.
A very sudden stoppage, such as is produced when the cathode ray meets an impassable barrier, produces the X-ray.
It is with such a supply of electricity conducted through a vacuum tube that the cathode ray and the Roentgen ray are produced.
What the cathode ray is to a certain branch of science, pure raw linseed oil is to carriage and wagon painting.
