Question

The diagram shows a clear glass lens.

A thin double concave lens.

Which best describes what happens when light rays move from air, through the lens, and back to air?

The light rays refract toward a central axis.
The light rays spread apart as they exit the lens.
The light rays converge toward a single point.
The light rays diverge before entering the lens.

Answer 1

The light rays spread apart as they exit the lens.

A double‑concave (thin) lens is a diverging lens, so parallel rays are bent outward and appear to come from a virtual focal point on the incoming side.
