Measuring Wavelength of Light with a Double Slit - PRACTICAL - A Level Physics

In this video I go through an AQA Physics A Level Required Practical that uses a double slit experiment to investigate the properties and to measure the wavelength of light. (This is AQA Required Practical 2.) A laser will diffract and interfere when shone through a double slit. A series of dark and bright fringes can be measured on a screen which will then allow you to calculate the wavelength of light. Be careful with the laser. Do not look at the beam or any reflected light from a shiny surface. See instructions for all the practicals at http://www.alevelphysicsonline.com/ye...
