Measurement of the wavelength of monochromatic light using a laser - Physics & Instrumentation, ATU
In this video a 600 lines/mm grating is used to determine the wavelength of light from a helium-neon laser.
This video can be used as a resource for an Undergraduate Physics laboratory or for Leaving Certificate/A Level revision.
