Webside focal point, F, in front of the lens (for a diverging lens). • The second ray (i.e., Ray 2) is drawn from the top of the object and through the center of the lens. This ray continues on the other side of the lens as a straight line. • The third ray (i.e., Ray 3) is drawn through the focal point, F, on the near side for WebThe focal length f is positive for converging lenses, and negative for diverging lenses. The reciprocal of the focal length, 1/f, is the optical power of the lens. If the focal length is in metres, this gives the optical power in dioptres (inverse metres). pub in weybourne norfolk
