A 2.00 µm-wide slit (assuming infinitely long) is illuminated with plane waves from a helium-neon laser of wavelengths 632.8 nm. Find the distance from the zeroth-order maximum to the first two irradiance nulls (zeroth to 1st and zeroth to 2nd), and to the first- and second-order irradiance maxima when the pattern is observed on a wall at Z= 1.0 m away. The small angle approximation [sin(0) ~ 0] is valid in some cases, but calculating the exact angle [x = sin 0 → 0 = sin¬1 x] leads you to an accurate answer in this problem.
