Consider two diffraction vk 51g5trao:bew)-ii gratings; one has y7krt l0/nm* 1az+sx f4000 lines per cm and the other one has 600lmxsza*r /0f 1 ktn7y+0 lines per cm. Make a statement comparing the dispersion of the two gratings.
A. The 4000-line grating produces the greater dispersion.
B. The 6000-line grating produces the greater dispersion.
C. Both gratings produce the same dispersion, but the orders are sharper for the 4000-line grating.
D. Both gratings produce the same dispersion, but the orders are sharper for the 6000-line grating.
