There are three basic types of cones in the retina, each of which responds maximally to a different wavelength
Indicate whether this statement is true or false.
Answer: True
Rationale: The trichromatic theory (or Young-Helmholtz theory) maintains that color vision is determined by three different cone types that are sensitive to short, medium and long wavelengths of light. Modern technology has been used to measure the amount of light that can be absorbed in cones and confirmed that each type responds to different wavelengths.
