WebJul 25, 2009 · Cathode Rays. The detection of cathode rays was a by-product of the investigation of the discharge of electricity through rarefied gases. The latter phenomenon had been studied since the early eighteenth century. By the middle of the nineteenth century it was known that the passage of electricity through a partly evacuated tube produced a … WebThe photoelectric effect was first observed in 1887 by Heinrich Hertz during experiments with a spark gap generator (the earliest device that ...

WebPreviously, atoms were known to be indivisible, but in 1897, J. J. Thomson, a British physicist, conducted the cathode ray experiment. He zapped atoms with electricity and observed that negatively charged particles were removed! He reasoned that atoms consisted of subatomic particles, electrons that were negatively charged particles. WebDec 29, 2024 · Additionally, J.J. Thomson's cathode ray tube experiment is what allowed for the discovery of the first subatomic particle, the electron. Computer monitors and …
WebA description of Thomson's Cathode Ray Tube experiment in which he determined the charge-to-mass ratio of the electron. WebIn this section I will discuss the grounds for belief in the existence of the electron by examining J.J. Thomson’s experiments on cathode rays. His 1897 experiment on cathode rays is generally regarded as the “discovery” of the electron. The purpose of J.J. Thomson’s experiments was clearly stated in the introduction to his 1897 paper.
