The tube is then exhausted until the cathode rays strike against the window.
Fluorescence is most efficiently excited by the cathode rays of a vacuum tube.
Unlike the cathode rays, they were not deflected by magnets; and neither did they seem to be reflected or refracted similarly.
The spectrum of the salts under excitation of cathode rays is a short continuous one in the blue region.
This experiment shows that the cathode rays are accompanied by a stream of negative electrification.
Fig. 220 shows a Crookes tube fitted with a metal plate, so that the cathode rays coming from C will strike it.
The power to emit light on heating may be retained for months after the exposure to cathode rays.
These rays are invisible and are even given out where the cathode rays strike the glass.
Diamonds, rubies and many minerals fluoresce brilliantly in the path of cathode rays.
The impact of cathode rays produces after a time perceptible changes in the glass.
cathode ray cath·ode ray (kāth'ōd')
A stream of electrons emitted by the cathode in electrical discharge tubes.
One of the electrons that is emitted in a stream from a cathode-ray tube.
|cathode ray |
A beam of electrons streaming from the negatively charged end of a vacuum tube (the cathode) toward a positively charged plate (the anode).
