WebCrookes placed a metal shape called a Maltese cross in the path of the cathode rays. The edges of the shadow were sharp, which suggested that the cathode rays travel in straight lines. Light casts shadows with sharp edges. Perhaps cathode rays were a type of light? Simulation of the Maltese Cross experiment.

Sir William Crookes OM FRS was a British chemist and physicist who attended the Royal College of Chemistry, now part of Imperial College London, and worked on spectroscopy. He was a pioneer of vacuum tubes, inventing the Crookes tube which was made in 1875. This was a foundational discovery that eventually changed the whole of chemistry and physics. WebThis animation describes J. J. Thomson’s second experiment involving the deviation of an electron beam in a vacuum tube, called a Crookes Tube. A partial vacuum (less than 10-6 atm) is maintained in the tube. A high voltage (between 10 and 100 kV) is applied between two electrodes.

WebDec 14, 2024 · Sir Joseph John Thomson was a British physicist and Nobel Laureate. He was well-known for the discovery of the electron. In 1897, he showed that cathode rays were composed of very small negatively charged particles. These particles later were named electrons. The apparatus of his experiment is called the cathode-ray tube (CRT). WebCrookes' experiment. By the 1870s the nature of electricity was unknown, and many experiments were done to determine its nature. Tubes with a low vacuum, possessing two metal electrodes (one at either end) were …
