a Only a limited number of maxima can be observed
(a) Only a limited number of maxima can be observed with a diffraction grating. The factor(s) that limit(s) the number of maxima seen is (are)
(a) (1) the wave-length, (2) the grating spacing, (3) both. Explain.
(b) How many maxima appear when monochromatic light of wave-length 560 nm illuminates a diffraction grating that has , and what are their order numbers?
