Measuring Wavelength of Light with a Diffraction Grating - PRACTICAL - A Level Physics

In this video I go through an AQA Physics A Level Required Practical that uses a diffraction grating experiment to investigate the properties and to measure the wavelength of light. (This is AQA Required Practical 2.) This is also the OCR A Level Physics PAG 5.1 Practical.

A laser will diffract and interfere when shone through a diffraction grating. The distance to the first, second and third order maxima can be measured which will then allow the wavelength of the light to be calculated. 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...

Thanks for watching,

Lewis
