Where in the eye is the image formed before signals travel to the brain?
AOn the cornea
BOn the iris
COn the pupil
DOn the retina
Answer & Solution
Correct answer: D. On the retina
1. Light enters through the pupil and passes through the lens.
2. It then lands on the retina, the light sensitive layer at the back of the eye.
3. Cells there turn the light into nerve signals that travel to the brain.
4. The pupil is only the opening that lets light in, so no image forms on it.
