A student is creating a model of a concave lens. The diagram shows her incomplete model.

Question

it shows a concave lens and arrows that represent rays of light pointing toward the lens. there are 5 of them, and they are all pointing straight across at the concave lens.

Which action would best complete her model?

A. The student should draw the light moving into the lens and then exiting in converging lines.
B. The student should draw the rays of light moving into the lens and then exiting at right angles.
C. The student should draw the rays of light moving into the lens and then exiting in a straight path.

Answer 1

To complete the student's model of a concave lens, the best action would be:

C. The student should draw the rays of light moving into the lens and then exiting in a straight path.

Concave lenses diverge light rays that are incident on them, causing them to spread out rather than converge. When parallel light rays pass through a concave lens, they appear to diverge from a focal point on the same side of the lens as the incoming light. Therefore, the correct representation involves the rays spreading out after passing through the lens.
