Light rays
A) striking the retina cause action potentials to be relayed to the brain.
B) are refracted by the cornea, lens, and humors.
C) are refracted as they pass through a convex lens.
D) that are converging, reach a crossing point called the focal point.
E) have all of these characteristics.

Question

Quizplus · Accepted Answer

All of the choices are true statements about light rays and their interactions with the eye and lenses. Light rays are refracted by the cornea, lens, and humors as they pass through the eye, and converging rays will meet at a focal point. These actions ultimately lead to the formation of an image on the retina, which triggers the transmission of action potentials to the brain. Therefore, all of the characteristics described in choices A-D are necessary for proper vision.
