-Young-Helmholtz trichromatic theory
A)capable of expressing psychophysical relationships when subjective intensities in-crease at a faster rate than physical intensities
B)proposal that the retina contains three different kinds of light-sensitive receptor cells,each one responding most strongly to light waves of one of the three prima-ry colors
C)states that the subjective intensity (S)of a stimulus measured in jnd units is pro-portional to the logarithm of its physical intensity (P)times some constant (k)

Question

Quizplus · Accepted Answer

The Young-Helmholtz trichromatic theory proposes that there are three types of cones in the retina, each sensitive to a different wavelength of light and corresponding to the primary colors red, green, and blue.

Note: Option A refers to Stevens' power law and option C refers to Fechner's law, which are not related to the Young-Helmholtz trichromatic theory.
