Final answer:
Tricolor light is composed of three colors, often referring to the primary colors of light: red, green, and blue. These primary colors can be combined to produce a wide range of colors, including white. The simplified theory of color vision explains our perception of colors through the stimulation of three types of cones in the eye.
Step-by-step explanation:
The term tricolor light refers to a light that consists of three colors. In the context of the visible light spectrum, these can be the primary colors of light: red, green, and blue. When mixed together in different combinations, these primary colors can create a wide range of other colors, including the creation of white light when combined at the right intensity.
Regarding the colors yellow, blue, and red:
- Part A asks to put these light waves in order according to wavelength, from shortest to longest. The order is: blue (shortest wavelength), green, yellow, orange, red (longest wavelength).
- Part B requires arranging these light waves according to frequency, from lowest to highest. The order is the reverse of the wavelengths: red (lowest frequency), orange, yellow, green, blue (highest frequency).
In color vision, the simplified theory purports that there are three primary colors that correspond to three types of cones in the human eye, and by stimulating these cones in different combinations, we perceive the wide spectrum of colors. This is why a combination of red, green, and blue light can create a whole rainbow.
