Aila is creating a model of a double convex lens. She draws horizontal lines to show light rays traveling toward the lens. How should Aila draw the light rays after they move through the lens?

• Aila should draw them converging to a point.

• Aila should draw them diverging without intersecting.

• Aila should draw them diffracting and moving upward.

• Aila should draw them continuing in the same direction.
