How do Lenses work? Concave Lens vs Convex Lens

Lenses are understood to be a curved and transparent piece of glass or plastic, which focuses and refracts light rays in a particular way. The curvature of the given object makes sure that the extent to the which light is bent and in which direction. It is mostly used in telescopes, spectacles and microscopes. Depending on the shape, these lenses can be grouped as a Concave lens or Convex lens.

Concave Lenses represent the type of lenses which are thin at the center than the borders. The shape of a concave lens is round inward which bends the beams outward, causing divergence of the rays of light falling on it, so it is known as a diverging lens. Hence, makes the objects look smaller and farther than they really are and the image formed is virtual, diminished and upright.

Convex Lenses are the lenses which are big at the center than the edges. The curve of the lens is outward, and as the light beams pass through the lens, it refracts them and brings them together, resulting in the convergence of light, due to which it is also known as a converging lens.
