Question

What is Convex Lens Used for?

Answer 1

Convex lens:

1. The convex lens converges light rays that travel parallel to its primary axis (i.e. converges incoming rays towards the principal axis) and is comparatively thick in the center and thin at the bottom and top edges.
2. Instead of curving inside, the edges curl outward. It is employed in front of the eye to severely bend incoming light so that the focal point shortens and the light correctly focuses on the retina.

Structure of a convex lens:

1. The middle of a convex lens is thicker than the sides.
2. Light rays are brought closer together as they pass through the lens (they converge).
3. The term "convex lens" refers to a convergent lens.
4. As parallel light beams pass through a convex prism, the refracted rays converge at a single point known as the primary focus.
5. The inside of the convex lens is curved.
6. Convex lens in the human eye helps us to see.
7. Convex lens is used to correct long-sightedness, also known as hypermetropia.
8. Convex lens is used in a magnifying glass.
9. Convex lenses are used in binoculars, telescopes, etc
