WebIn Crookes experiment, he placed an object in the path of the ray. He noticed a shadow on the positive electrode. He was able to conclude that 'something' had traveled from the negative end to the positive end. He hypothesized that the glow was made up of small particles. Describe how Thomson's work expanded upon Crookes. (2.01) 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).

Alternatively, the tube could also be connected to a vacuum pump. Observations The tube emits a glow in a straight line until the magnet is brought near. The magnet deflects the glow into a bent line. Explanations pasta con peperoni alla sicilianaWebIn 1878, Sir William Crookes, a British scientist, displayed the first cathode rays using a modification of the Geissler apparatus.

"WebNot every Crookes radiometer was made equal. Next experiment was more interesting by using a mill with smaller static friction, therefore more sensitive. As expected, in the forward direction, it just started quicker and spun faster. When the torch was pointed to a white vane, it started to move immediately but slowly. " - Crooks experiment
