The intensity of light with wavelength traveling through a diffraction grating with N slits at an angle is given by l(θ) = N2 sin2k/k2, where k = (π Nd sin θ(/λ and is the distance between adjacent slits. A helium-neon laser with wavelength λ = 632.8 x 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 apart. Use the Midpoint Rule with to estimate the total light intensity emerging from the grating.
