The difference between converging and diverging lenses. How to draw a lens diagram. The application of lenses. Identifying defects of vision and how they are corrected using lenses.

To clarify all your doubts about the concave lens and convex lens, students can read this article. Here, the difference between a concave lens and a convex lens has been discussed in detail.

In this Closer Look segment on Lenses, we compare and contrast concave and convex lenses by drawing ray diagrams and investigating the thin lens, magnification, and center of curvature equations.

Lenses are used in cameras, telescopes, binoculars, microscopes and corrective glasses. A lens can be converging (convex) or diverging (concave).
