WebMar 28, 2024 · A concave lens is flat in the middle and thicker at the edges. ... The lens whose refracting surface is upside down is called a convex lens. ... Lens formula: A lens formula may be defined as the formula which gives the relationship between the distance of the image (v), the distance of the object (u), and the focal length (f) of the lens. ... WebAlthough we derived this equation for refraction at a convex surface, the same expression holds for a concave surface, provided we use the following sign convention: R > 0 if … WebSpherically Refracting Surfaces 1.
