1.	define focal length of a convex mirror write the relationship between focal length and radius of curvature of a convex mirror
Answer» Answer: Focal LENGTH is the distance between the center of a convex lens or a concave mirror and the focal point of the lens or mirror — the point where parallel RAYS of light meet, or converge. The focal length (f) of a lens is the distance between the center of the lens and the point at which the reflected light, of a beam of light travelling parallel to the center LINE, meets the center line (principal axis). The RADIUS of curvature (R) is the radius of the lens that forms a complete sphere.
