What step would most effectively finalize her model?
(1 point)

The student should depict the light rays entering the lens and then emerging in a straight trajectory.

The student should sketch the light rays entering the lens and then exiting at right angles.

The student should illustrate the light entering the lens and then emerging in converging lines.

The student should illustrate the light entering the lens and then departing in lines that are spreading out.

To finalize the model of a concave lens, the student should illustrate the light entering the lens and then departing in lines that are spreading out.

Concave lenses cause parallel light rays to diverge after passing through them, making it appear as if the rays are originating from a focal point on the same side as the incoming light. Thus, the correct step is:

The student should illustrate the light entering the lens and then departing in lines that are spreading out.
