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 sin2(k)/k2, where k = (πnd sin θ)/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.
