Question

Quizplus · Accepted Answer

Fechner's law states that the subjective intensity (S) of a stimulus measured in jnd units is proportional to the logarithm of its physical intensity (P) times some constant (k).

Answer: B 
 Trichromatic theory is the 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 primary colors.

Answer: A 
 Power function describes the relationship where subjective intensities increase at a faster rate than physical intensities. Fechner's law is not related to power function.
