WebExercice1: (Expérience de J.J. Thomson 1897) Dans l’expérience de J.J. Thomson, on réalise la déviation d’un faisceau d’électrons à l’aide d’un champ électrique E et on mesure la déviation Y sur l’écran. La déviation du faisceau électronique est annulée par l’action antagoniste d’un champ magnétique B qui agit dans le Web1 nov. 2008 · Six years later, at the age of 24, he won another scholarship, this time to Cambridge University to work with the physicist J.

WebThree experiments led him to this.: irst, in a variation of an 1895 experiment by Jean Perrin, Thomson built a cathode ray tube ending in a pair of metal cylinders with a slit in them. These cylinders were in turn connected to an electrometer, a device for catching and measuring electrical charge. Perrin had found that cathode rays deposited an ... Web29 dec. 2024 · J.J.
