B) absolute activity of a single cone
C) difference between cone and rod activity
D) relative activity of short, medium, and long wavelengths

Question

Quizplus · Accepted Answer

The trichromatic theory proposes that the human eye has three types of color receptors or cones that strongly respond to different wavelengths of light: short (blue), medium (green), and long (red). Our perception of color is determined by the relative activity of these cones when they are stimulated by different wavelengths of light. Therefore, the most important factor in determining the color we see is the relative activity of short, medium, and long wavelengths of light.
