II. Converging or Diverging?

Identify whether the lens involved is converging or diverging.

1. This type of lens is also called a convex lens.

2. Parallel light rays meet at the focus after leaving the lens.

3. This lens is thick at the middle but thin at the edges.

4. Parallel light rays spread out upon hitting the surface of this lens.

5. This type of lens is thin at the middle but thick at the edges.

6.

7.

8. The refracted rays meet at the virtual focus when extended

backwards.

9. The refracted rays intersect at a point after leaving the lens.

10. We have this type of lens in our eyes.
