In the physics we have Helium-Neon lasers that produce a wavelength of 632 nm. Suppose that we have a diffraction grating that is unlabeled (so we don’t know its slit spacing) and a violet laser pointer whose wavelength we wish to determine. We then shine the Helium-Neon laser on the grating, project the diffraction pattern onto a screen that is 1.00 m from the grating and measure the positions of the diffraction maxima on the screen. Next we remove the...
