The intensity of light with wavelength traveling through a diffraction grating with slits at an angle is given by
where and is the distance between adjacent slits. A helium-neon laser with wavelength meters is emitting a narrow band of light, given by through a grating with 10,000 slits spaced meters apart. Use the Midpoint Rule with = 10 to estimate the total light intensity
emerging from the grating.
Note: Make sure your answer is correct to four decimal places.
