True1.True or False light enters the eye through the pupil and cornea.?
The pupil is an opening in the center of the iris that allows light to enter the eye. Together with the lens, the cornea refracts light, and as a result helps the eye to focus. The cornea contributes more to the total refraction than the lens does, but, whereas the curvature of the lens can be adjusted to ';tune'; the focus depending upon the object's distance, the curvature of the cornea is fixed.1.True or False light enters the eye through the pupil and cornea.?
That is true, but to be technically correct, it would pass through the cornea first, then the pupil.
