Which lens concave or convex forms the image wider?
Only a convex lens forms any kind of real image and the size of the image is dependent upon the focal length (hence the curvature and and substance) of the lens. A concave lens forms a virtual or imaginary image in front of the lens. It is one that cannot be projected onto a surface. Perhaps what you mean has to do with convergence and divergence. A convex lens causes light rays to converge (come together at a point), while a concave lens causes rays to diverge.
