Electrons and Atoms

Synopsis: Demonstrates some classic physics experiments relating to the properties of electrons, showing that electrons travel in straight lines and carry momentum when they interact with objects. J J Thompson, the discoverer of the electron, measured the charge to mass ratio by a clever experiment he performed in 1987 in which he balanced opposing electrostatic and magnetic deflections of an electron beam. Finally, a modern mass spectrometer is used to show that neon gas is made up of atoms of three different masses - isotopes of neon.

Notes: NB. As of May 2016 Open University Worldwide are no longer distributing DVDs. They have posted this message on their website: ‘Unfortunately Open University Worldwide Limited has decided that product sales are no longer viable given the reduced funding to Higher Education institutions and diminishing demand for the products we have traditionally stocked. At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
