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.

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.

Microwave Interferometer
Part 1: Double Slit Experiment
The double slit apparatus can be used to find the wavelength of the microwaves using Young’s Slits equation.
Part 2: Using the Interferometer
The microwave interferometer instructs students on the basics, and the box has support material which discuss the famous experiment.
Part 3: Packing up the Box
Phil Furneaux demonstrates how to safely pack away the equipment.
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.

Planck's Constant
Part 1: Setting up Planck's Constant experiment
Planck’s Constant must be one of the most used in modern physics. This experiment uses the photoelectric effect and Einstein's equation to measure the constant h. The BOX also contains a class set of LED boxes where the constant can be measured using a voltmeter and an ammeter using the equation E = hf. A teacher must be present at all times during this experiment due to high voltages and the danger of the UV light source.
