Concave and Convex Lenses - The type of lenses which converge the light beam coming from the source to one point on the other side to form an image is called as a convex lens, while the concave lens which is thinner at the centre and gets thicker as we move towards the edges is called as Concave lens. The lens has a focal length of 35 millimeters. <> 6. 0000020147 00000 n A lens is a . Concave and convex are used in many lenses… 4.
