CATHODE RAY Meaning and
Definition
-
Cathode ray refers to a stream of electrons emitted by the negatively charged electrode, called the cathode, in a vacuum tube or cathode ray tube (CRT). It is characterized by its ability to produce a visible spot of light or a glow when it strikes a fluorescent screen located at the other end of the tube. This phenomenon was first observed and studied by Sir William Crookes in the late 19th century.
The cathode ray is generated when a high voltage is applied across the electrodes of the vacuum tube, causing a flow of electrons from the cathode towards the positively charged anode. These high-speed electrons form a narrow beam that travels in a straight line. The cathode ray is negatively charged and can be deflected by electric or magnetic fields, allowing for manipulation and control of its path.
Cathode ray technology formed the basis for early television sets and computer monitors, where the stream of electrons was used to scan and display images on a phosphorescent screen. This technology revolutionized the world of visual display and formed the foundation for the development of modern display technologies.
In addition to its importance in visual displays, further research on cathode rays led to significant breakthroughs in the field of particle physics, particularly in the discovery and understanding of electrons as subatomic particles. Today, cathode ray technology has been largely replaced by more advanced display technologies such as liquid crystal displays (LCDs) and light-emitting diodes (LEDs).

Etymology of CATHODE RAY
The word "cathode ray" has a Greek origin. It is derived from the Greek words "kathodos" (κάϑοδος) and "ray" (ἀκτίς). "Kathodos" means "descent" or "way down", and "ray" refers to a beam or stream of light. The term "cathode ray" was first used in the late 19th century to describe the stream of electrons emitted by the cathode in a vacuum tube or cathode ray tube (CRT).
