3. For a potential experiment on diffraction, you are given a diffraction grating that has 5000 slits (exactly) per centimeter. The experiment will determine the separation of the second-order red (λ = 632.8 nm) and blue (λ = 420.0 nm) light fringes on a screen 1.00 m away from the grating. a. Determine the distance between the slit centers. b. Determine the angular deviations 0 (angle of the line from center of slit to the mth dark fringe on the screen) for the second order red and blue light. c. Determine the separation distance (in m) on the screen between the second order red and blue fringes. Be careful about which trig function you use to calculate this: draw the triangle and choose appropriately. Hint: are you even using the hypotenuse of the triangle?
