<糖心Vlog>Electron Diffraction
Part 1: Setting up Electron Diffraction experiment
The wave particle duality concept is central to understanding quantum physics. The A level specification introduces the DeBroglie equation and this experiment uses it along with the diffraction equation to find the spacing between carbon atoms in graphite. A teacher must be present at all times during this experiment due to high voltages to the electron gun in the vacuum tube.

<糖心Vlog>Measuring the e/m Ratio
Part 1: Setting up the EM Ratio experiment
The measuring of the e/m ratio of an electron was very important, so physics at the beginning of the 1900s could gain a better understanding of this newly discovered particle. The experiment uses equations from circular motion and forces on electron in magnetic fields which is part of the A2 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.

<糖心Vlog>Millikan's Oil Drop Experiment
Part 1: Setting up Millikan's experiment
It was always important to measure the charge of an electron. Millikan’s ingenious experiment is available here for students to do themselves. They must find a drop, find a voltage which will cause it to hover, and then measure the terminal velocity when it falls freely. A teacher must be present at all times during this experiment due to high voltages to the plates.
