This lab was designed to introduce us to a diffraction grating, by having us perform the classic Young’s double slit experiment. Figure 1: Assemble the components as shown in figure 1. Place the 35mm slide, which is the diffraction mosaic, in front of the laser. The separations are 45, 58, 75, and 100 microns respectively. Figure 1 Wavelength, λ, of the laser is known to be 0.6328[um]. The distance away from the grating to the screen is measured and recorded to be 63[cm]. To solve for the period - d: ( 29 θ λ sin d = Mosaic Width ө d 45 microns 8 [mm] 3.633˚ 9.986 [um] 58 microns 7 [mm] 3.179˚ 11.41 [um] 75 microns 5 [mm] 2.272˚ 15.96 [um] 100 microns 4 [mm] 1.818˚ 19.94 [um] Now set up the same experiment with the diffraction grating. Again the wavelength, λ, of the laser is known to be 0.6328[um].
