Hilda looks at a CD and sees different colors. Which best explains why she sees different colors when light strikes a CD?

A CD’s closely spaced grooves act like a diffraction grating. Different wavelengths of light bend at different angles, so they reach Hilda’s eyes in separate directions and appear as different colors. This is why “different wavelengths of light bend at different angles” is the best choice.
