According to the trichromatic theory of colour vision, cones can be categorized based on
A) the location of a cone in one of three parts of the fovea
B) the peak sensitivity of a cone to the intensity of a light source
C) the peak sensitivity of a cone to one of three spectrums of wavelength
D) the level of inhibition in a cone relatively to three wavelengths of light

Question

Quizplus · Accepted Answer

According to the trichromatic theory of colour vision, there are three types of cones in the human eye, each with a peak sensitivity to a different range of wavelengths. These cones are commonly referred to as blue, green, and red cones, but they are more accurately described as short-wavelength (S), medium-wavelength (M), and long-wavelength (L) cones. Therefore, cones can be categorized based on the peak sensitivity of a cone to one of three spectrums of wavelength.
