Relationship of focal length and center curvature

relationship of focal length and center curvature

The focal length of an optical system is a measure of how strongly the system converges or For a thin lens in air, the focal length is the distance from the center of the lens to the For the case of a lens of thickness d in air (n1 = n2 = 1), and surfaces with radii of curvature R1 and R2, the effective focal length f is given by the. What's the relationship between the center of curvature and the focal length of a convex mirror and describe how light beams are directed towards the focal point . The relationship between the focal length f and radius of curvature r is r = 2f. In deriving this relation, we have assumed that the aperture of the mirror is small.
