The first CRT was developed by Karl Ferdinand Braun (Germany) in 1897.
The cathode ray tube was not discovered it was invented by Ferdinand Braun
cathode ray-tube was discovered by J.J. thomson.
The electron was discovered by using cathode ray tubes. When it was discovered that the cathode ray diverted away from the negative end of a magnet to the positive end, it revealed that there was a negative particle present in the ray.
The inventor of the cathode ray tube was Kalman Tihanyi. Tihanyi was a Hungarian physicist and inventor, born in Slovakia in 1897.
The Cathode Ray Tube is called CRT, but I don't know of any "modern day" name. I know it was discovered by J.J. Thomson, who discovered electrons through the Cathode Ray Tube.
Electrons
J.J. Thomson used a cathode ray tube to discover electrons. By passing an electric current through the tube, he observed the deflection of a beam of electrons, which led to his conclusion about the existence of electrons.
J. J. ThomsonJ. J. Thomson did the cathode ray experiment where he discovered the existence of electrons.
electron
The cathode ray experiment was discovered by British physicist J.J. Thomson in 1897. Through this experiment, he was able to demonstrate the existence of negatively charged particles (electrons) and their properties.
J.J.Thomas discovered that atoms have negatively charged particles called electrons. He discovered this using the Cathode Ray. The cathode ray is a beam of electrons emitted by the cathode of an electrical discharged tube.
Thomson discovered cathode rays when he was working with electrons. He was performing experiments with the electrons when one of them became electrically charged and a beam of light came from it, this creating a cathode ray.
