What is the Trichromatic Theory?a) It suggests our eyes have two types of cones, one for blue and one for yellow.b) It proposes there are six types of cones in our eyes, each for a different color.c) It claims color vision relies on the rods in our eyes, which detect various light wavelengths.d) It states we have three types of cones in our eyes, each for short, medium, or longwavelengths.e) It argues colors are perceived through the absorption of light by cells called cones in our eyes.
Question
What is the Trichromatic Theory?a) It suggests our eyes have two types of cones, one for blue and one for yellow.b) It proposes there are six types of cones in our eyes, each for a different color.c) It claims color vision relies on the rods in our eyes, which detect various light wavelengths.d) It states we have three types of cones in our eyes, each for short, medium, or longwavelengths.e) It argues colors are perceived through the absorption of light by cells called cones in our eyes.
Solution
The correct answer is d) It states we have three types of cones in our eyes, each for short, medium, or long wavelengths. The Trichromatic Theory, also known as the Young-Helmholtz theory, proposes that the human eye has three types of receptors with differing sensitivities to different light wavelengths. One receptor is sensitive to the color blue (short wavelengths), another to green (medium wavelengths), and the third to red (long wavelengths).
