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

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

Discharge Tube (Crookes Tube) | Definition, Working

discharge tube

Definition of Discharge Tube or Crookes Tube An electron tube contains gas vapor at low pressure and through which conduction occurs when a high voltage is applied. A discharge tube (also Crookes–Hittorf tube) is an early experimental electrical discharge tube, with partial vacuum, invented by English physicist William Crookes and others around 1869-1875, cathode rays, … Read more
