The dispersion of a diffraction grating, such as the one shown at the right, is the angle of separation per ?m of wavelength, ?? /??. It depends on the order of the diffraction (n), the distance between grooves (d) and the angle of the emerging light (?). Calculate the dispersion at ? = 23° of the first order diffraction for a grating with 1.00 × 103 grooves per centimeter. Give the answer in °/?m?
When numbers are very small or very large, it is convenient to either express the value in scientific notation and/or by using a prefix with the unit.
