Question

Quizplus · Accepted Answer

The Young-Helmholtz theory, also known as the trichromatic theory, proposes that there are three types of cones in the retina that are each most sensitive to a different range of wavelengths of light (short, medium, and long). This theory is directly supported by evidence that some cones are more sensitive to certain colors, such as red, green, or blue.
