If you move farther from a paper with many tiny dots,the blue dots start to look black,although you can still see the tiny red and green dots.Why?
A)You have fewer short-wavelength cones than the other types.
B)Short-wavelength light excites cones but not rods.
C)Short-wavelength light cannot travel as fast or as far.
D)The lens cannot focus short-wavelength light as well as the other wavelengths.

The human retina contains three types of cone cells, each sensitive to a different wavelength of light (short, medium, and long). We have fewer cones that are sensitive to short wavelengths (blue light) compared to cones for medium (green) and long (red) wavelengths. As you move away from the paper, the blue dots blend together and may appear black due to the lower density of short-wavelength cones, making it harder to distinguish the blue color at a distance.
