Anode Rays (Canal Rays) | Experiment, Procedure

anode rays

Definition of Anode Rays The streams of positively charged particles are called anode rays or positive rays, or canal rays. Discovery of Anode Rays Anode rays (or Canal rays) were observed in experiments by a German scientist, Eugen Goldstein, in 1886. Goldstein used a gas discharge tube that had a perforated cathode. A “ray” is … Read more

Cathode Rays | Definition, Discovery, Experiments

cathode rays

Definition of Cathode Rays Cathode rays are the beam of electrons traveling from the negatively charged Cathode to the positively charged anode at the other end of the vacuum tube. These Cathodes travel in a straight-line path at high speed when a voltage difference is applied to the electrodes. The detection of cathode ray was … Read more

Cathode Ray Experiment | Apparatus, Working

cathode ray experiment

Cathode Rays Experiment J.J.Thomson conducts three experiments with cathode ray experiment. Experiment-1 In 1897, great physician J.J. Thomson conducted his first cathode ray tube experiment to prove that rays emitted from an electron gun are inseparable from the latent charge. He built his cathode ray tube with a metal cylinder on the other end. The … Read more

What is an Electron | Definition, Discovery, Examples

what is an electron

Definition of Electron An electron is a negatively charged subatomic particle. It can be either free (not attached to any atom) or bound to the nucleus of an atom. Electrons in atoms exist in spherical shells of various radii, representing energy levels. The larger the spherical shell, the higher the energy contained in the electron. … Read more
