Adiffraction grating is ruled with 100,000 lines in a distance of 8 cm and used in the first order to study the hyperfine structure of a spectral line at 423 nm. how does the chromatic resolving power compare to that of a equilateral glass prism with a base of 8 cm and refractive indices of 1.5608 at 401nm and 1.5462 at 445 nm? assume the grating was ruled with a blaze to create maximum efficiency at 423 nm (littrow configuration), what is the blaze angle for the ruled grating?
