Part 1) In an experiment, you direct a coherent light source with wavelength λ = 476 nm towards a diffraction grating and observe the first maximum occurring at 0 = 0.252 rad. You switch on a second light source with wavelength X' = 533 nm. Use Rayleigh's criterion to determine the minimum number of rulings such that you can distinguish the first maximum of the second light source from the first maximum of the first light source. N> Part 2) Calculate the dispersion of the grating at the first maximum. -1 D = m Part 3) Consider a grating with 6 rulings with intensity Io at each ruling. What is the maximum intensity at the central maximum? I = Io Your light source is unpolarised and you cover 3 of the 6 rulings with a polariser. What is the maximum intensity at the central maximum? I = Io

(a) How wide (in mm) is the central maximum (the central, bright fringe), as measured on the screen? mm (b) How wide (in mm) is either of the two first-order bright fringes, as measured on the screen? mm A technician directs monochromatic light toward a single slit in an opaque barrier. The light has a wavelength of 500 nm and the slit is 0.170 mm wide. The light that passes through the slit creates a diffraction pattern on a screen, which is 1.60 m from the slit. Need Help?
