Please double check and make sure the answer is correct thanks!

The dispersion of a diffraction grating, such as the one shown in the image, is a measure of the angular separation of adjacent wavelengths, /. It depends on the order of the diffraction (n), the distance between grooves in the grating (d) and the angle of the emerging light (). Calculate the dispersion of a first order diffraction for light emerging at =15.0 when a grating with 1.30103 grooves per centimeter is used. Report the answer in degrees per micrometer. = %m
