Charles Francis Jenkins and John Logie Baird both wowed public audiences with their new image-transmitting devices in 1925.

It put to rest a long history of experimentation seeking to determine whether or not a “cathode ray” as the electron ... CC 4.0. The suite of experiments that led Thomson to identify the ...

There was debate over whether the cathode ray was a wave phenomenon like light or a stream of negatively charged particles. JJ Thomson effectively resolved the debate in 1897 by performing a clever ...

In 1897, English physicist Joseph John Thomson discovered electrons while conducting experiments with cathode-ray tubes. He called electrons “corpuscles”. Cathode Ray Tube. Source: Chemistry ...

In 1895, Wilhelm Röntgen discovered X-rays while experimenting with cathode rays and crystals, leading to the realization that invisible rays could cause fluorescence and penetrate lightproof ...

The experiment is described in a study published ... The researchers used the world’s largest and most powerful X-ray laser: the European X-Ray Free-Electron Laser (European XFEL) located ...

The cathode ray tube amusement device is the earliest known interactive electronic game to use a cathode ray tube (CRT). It is a device that records and controls the quality of an electronic signal.

Physics experiments have changed the ... But exactly what caused this effect, called a cathode ray, was unclear. Then, in 1897, physicist J.J. Thomson discovered that by applying a magnetic ...
