A diffraction grating is made up of slits of width = 300 nm with separation = 1150 nm. The grating is illuminated by monchromatic plane waves of wavelength ? = 560 nm at normal incidence. How many maxima are there in the full diffraction pattern? What is the angular width of a spectral line observed in the first order if the grating has 1300 slits.
