A laser with a wavelength of À = 410 nm is incident on a diffraction grating. The m = 3 maxima appears a distance of y = 2.90 cm from the central maximum when the screen is placed X = 86 cm from the grating. What is the diffraction angle for this m = 3 maxima? 0 What is the slit separation, d, in nm? d = nm How many lines/cm does the grating have in lines lines cm ?
