Measuring the e/m Ratio
The measuring the e/m ratio of an electron was very important so physics could gain a better understanding of this particle.
The measuring the e/m ratio of an electron was very important to physics at the beginning of the 1900s. It allowed scientists to gain a better understanding of this newly discovered particle. The experiment uses equations from circular motion and forces on electrons in magnetic fields which is part of the AS physics syllabus as well as being in the turning points in physics module. The experiment needs a fully darkened space. A teacher must be present at all times during this experiment due to high voltages to the electron gun in the fine beam tube.
