Assume that the limits of the visible spectrum are arbitrarily chosen as 436 and 699 nm. Calculate the number of rulings per millimeter of a grating that will spread the first-order spectrum through an angle of 19° .
i think u set up two eqns, one would have theta unknown and both would have d unkown, and d is your gradiunts/mm
