But for many materials I have read so far, it says that: "the focal length of a concave lens is 8 cm." WebNov 21, 2024 · Optics Sign Conventions In the case of a convex lens, the object distance is negative as it is placed before the mirror. And since the speed of the light remains constant when traveling in the vacuum or simply in a single medium , we can also say that the path taken between two points by a ray of light is the shortest one.

WebSign convention in the case of a convex mirror: Since, object is always placed in front of the mirror hence the sign of object is taken as negative. Since, the centre of curvature and focus lies behind the convex mirror, so sign of radius of curvature and focal length are taken as + (positive) in the case of convex mirror.
