WebA thin lens is one whose thickness is negligible in comparison to the image and object distance. A convex lens is thicker in the center than at the edges and can also be called a positive lens or converging lens. A concave lens is thinner at the center than at the edges and can also be called a negative lens or a diverging lens. Webindex of the lens, we can find the focal length of the lens. Normally, the thickness of the lens must be considered. For a thin lens, we use the lens maker’s equation () = − − 1 2 1 1 1 1 r r n f r is negative for concave faces and positive for convex (as 6 r is negative for concave faces and positive for convex (as seen from the object). r chronic rhinitis catWebStep 1: Determine if the focal length is positive or negative.

WebAn ideal thin lens with two surfaces of equal curvature would have zero optical power, meaning that it would neither converge nor diverge light. All real lenses have nonzero thickness, however, which makes a real lens with identical curved surfaces slightly positive. WebApr 3, 2007 · For this question, assume that the index of refraction of diamond is 2.39, that of glass is 1.65, that of water is 1.30, and that of air is extremely close to 1. A thin lens made of glass has a focal length in air of 16.1 cm. A lens of exactly the same shape is then made from diamond. HINT: Review the derivation of the thin lens formula.

The focal length, f, of a lens in air is given by the lensmaker's equation: where n is the index of refraction of the lens material, and R1 and R2 are the radii of curvature of the two surfaces. For a thin lens, d is much smaller than one of the radii of curvature (either R1 or R2). In these conditions, the last term of the Lensmaker's equation becomes negligible, and the focal length of a thin lens in air can be approximated by
