Concave lenses are the lenses in which both surfaces are curved inward. These form virtual, erect and diminished images. These have negative focal length.
Convex lenses are the lenses in which both surfaces are curved outward. These form real, inverted and enlarged images. These have positive focal length.
A convex lens or converging lens focuses the light rays to a specific point, whereas a concave lens or diverging lens diverges the light rays. A lens is a transparent material (either curved or flat surface) based on the principles of refraction
