The intensity of light with wavelength λ traveling through a diffraction grating with N slits at an angle θ is given by I(θ) = N2 sin2k/k2, where k = (πNd sinθ)/λ and d is the distance between adjacent slits. A helium-neon laser with wavelength λ = 632.8 × 10−9 m is emitting a narrow band of light, given by −10−6 < θ < 10−6, through a grating with 10.000 slits spaced 10−4 m apart. Use the Midpoint Rule with n = 10 to estimate the total light intensity
