ElectronDuring the 1870s, the English chemist and physicist Sir William Crookes developed the first hode ray tube to have a high vacuum inside. He then showed in 1874 that the hode rays can turn a small paddle wheel when placed in their path. Therefore, he concluded that the rays carried momentum. Furthermore, by applying a magnetic field, he was able to deflect the rays, thereby demonstrating ...
