Question

What ratio of wavelengths is primarily responsible for color vision?

a. Red, Green, Yellow
b. Green, Blue, Orange
c. Red, Blue, Violet
d. Yellow, Blue, Red

Answer 1

The wavelengths primarily responsible for color vision match the sensitivity of the three types of cones in the eye, which are most responsive to red, green, and blue light.

Step-by-step explanation:

The ratio of wavelengths primarily responsible for color vision corresponds to the activity of three types of color-sensing cones in our eyes. These cones are sensitive to different segments of the visible spectrum, usually associated with the colors red, green, and blue. In terms of wavelength, the primary colors of visible light, running from long-wavelength light to short, are red (approximately 700 nm), green (approximately 497 nm), and blue (approximately 470 nm), as these are the colors that our cones are most responsive to. While red, orange, yellow, green, blue, indigo, and violet make up the mnemonic ROY G BIV for the spectrum colors, the red, green, and blue are fundamental for color perception in human vision.
