noun A stream of electrons emitted by the negative electrode in a vacuum tube or cathode-ray tube.
In physics, cathode ray refers to a stream of electrons emitted by the negative electrode in a vacuum tube, used in cathode ray tubes for displays and in electron microscopes for imaging.
In electronics, cathode ray tubes are used in television sets, computer monitors, oscilloscopes, and other display devices to produce images through the manipulation of electron beams.
In telecommunications, cathode ray tube displays were commonly used in radar systems for displaying information on a screen.
In medical imaging, cathode ray tubes were historically used in devices like fluoroscopes for viewing internal structures of the body in real-time.
In the history of science, the discovery and study of cathode rays played a significant role in the development of modern physics and the understanding of electrons.
In physics, cathode rays are used in cathode ray tubes (CRTs) to create images on a screen by manipulating electron beams.
Cathode ray tubes are used in oscilloscopes and old television sets to display waveforms and images.
Cathode rays are used in X-ray tubes to produce X-rays for medical imaging.
Cathode ray tubes are used in mass spectrometry for ionization and detection of particles.
Cathode ray tubes can be used for thin film deposition in materials science research.
