A student researching the eye has taken notes:
• The human eye detects light through 130 million photoreceptors • Rods detect light intensity while cones detect color • The brain interprets signals into images we see • Eyes adjust to light levels through pupil dilation • Color blindness affects about 8% of men
The student wants to explain how we see color.
The human eye contains approximately 130 million photoreceptors.
We see color through cone photoreceptors in the eye, which detect different wavelengths of light and send signals that the brain interprets as color.
Color blindness affects approximately 8% of men but far fewer women.
Eyes adjust to varying light levels through pupil dilation.
Correct Answer: B
Choice B. Cones detecting wavelengths that brain interprets explains color vision.
