Diffraction gratings are used in interference experiments and allow for the separation of light into its constituent wavelengths. This is incredibly useful to analyse light that is being emitted by bodies. • In this video I demonstrate their use, provide the mathematical basis and discuss some applications • Watch and find out • ERRATA: at 8:22 I state 300 line per mm is 3 million lines per meter when in fact its 300,000 lines per meters. the final 'd' value is correct. • Intro to spectroscopy - • spectroscopy explained - with Crooked... • The use of spectroscopy in astronomy - • Stellar Spectroscopy - what can we le... • Like what I do?
