Convex lens

Definition

A convex lens is a lens that converges light rays to a focal point, making objects appear larger. It is thicker in the middle than at the edges.

5 Must Know Facts For Your Next Test

1. Convex lenses are essential components in microscopes.
2. They can produce both real and virtual images depending on the object's distance from the lens.
3. The focal length of a convex lens is the distance from the center of the lens to its focal point.
4. Convex lenses are used to correct hyperopia (farsightedness).
5. The magnification power of a convex lens depends on its curvature and material.
