Diffraction Gratings - A Level Physics

This video introduces and explains diffraction gratings for A Level Physics. If you shine light, or other types of EM radiation, through a series of small slits, the waves interfere causing constructive and destructive interference at certain points. We can then use this method to calculate the wavelength of light. It is also why DVDs and CDs make beautiful rainbows.
