Consider two diffraction gratings; one has 4000 lines per cm and the other one has 6000 lines per cm. Make a statement comparing the dispersion of the two gratings. Consider two diffraction gratings; one has 4000 lines per cm and the other one has 6000 lines per cm. Make a statement comparing the dispersion of the two gratings. a. Both gratings produce the same dispersion, but the orders are sharper for the 6000-line grating.
b. Both gratings produce the same dispersion, but the orders are sharper for the 4000-line grating.
c. The 6000-line grating produces the greater dispersion.
d. The 4000-line grating produces the greater dispersion.
