Focal length of diverging lens
WebFeb 8, 2009 · f=focal length di=image distance do=object distance hi=image height ho=object height The Attempt at a Solution The first thing I do is plug in values for the thin lens equations and solve for di (do and f are given). I end up getting: 18/di=-2.5 di=-7.2 cm So the distance of the image from the lens is -7.2 cm. However, this is where I get … WebWhat is the focal length of the lens? Solution: Reasoning: The focal length of a thin lens is related to the radii of curvature of its two surfaces. 1/f = (n2 - n1)(1/R1 - 1/R2). Details of the calculation: Both R1and R2are …

WebIf you have myopia or nearsightedness, you would use diverging lenses (concave) to shift the focus of your eye lens backwards so that it can focus on the retina. Just the opposite goes for hypermetropia or farsightedness, in which you would use converging (convex) lens to bring the focus closer. In astigmatism, you would use cylindrical lenses. how to save recording on obsWebA near-sighted person might correct his vision by wearing diverging lenses with focal length f = -50 cm .
