Focal length and refractive index relation
WebA thin plastic lens with index of refraction n = 1.67 has radii of curvature given by R1 = 12 0 cm and R2 = 40.0 cm. Determine (a) the focal length of the lens, (b) whether the lens Ls converging or diverging and the image distances for object distances of (c) infinity, (d) 8,00 cm, and (e) 50.0 cm. WebMar 15, 2024 · It is used to manufacture lenses of the desired focal length. Lens Maker’s Formula is given as 1 f = (v − 1)( 1 R1 − 1 R2) Where v is the refractive index of the material. f is the focal length. R1 is the radius of curvature of the first lens. R2 is the radius of curvature of the second lens. Now, as per the Power of a Lens Formula, P = 1/f
