This chemistry and physics video tutorial provides a basic introduction into the cathode ray tube experiment. JJ Thompson used this experiment to conclude that all atoms contain negatively charged particles known as electrons. Using this experiment, he was able to calculate the charge to mass ratio of an electron.
