In the characterization of a diffraction grating, a student used a blue laser (λ =442 nm ). The screen where she was projecting the laser was 1.75 m from the grating and the first order of diffraction appeared 1.65 m away from the bright spot of the undiffracted beam. Calculate the spacing of the grating in mm−1
