WebMedium Solution Verified by Toppr Since from lens makers formula we can observe that focal length of lens is inversely proportional to refractive index of medium of lens . Hence net refractive index of lens decreases when it is dipped in a denser medium than air, hence focal length increases. WebMar 5, 2024 · Apparently, focal length f is inversely proportional to the refractive index of the medium μ. Since, Optical Power P = 1 f. This should imply that optical power is …
WebThe focal length of a mirror is represented as f and is defined as the distance between the focus and the pole of the mirror. The radius of curvature is represented as R and is … 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
WebThe following typical equation is used to determine relation between focal length of lens, distance of object as well as distance of image. 1/f = 1/v + 1/u Where, f is focal length v is distance of image from optical center u is distance of object from optical center Get answers from students and experts Ask Derivation of Lens Formula Web1 f = ( n − 1) ( 1 R 1 − 1 R 2) where, f is the focal length (half the radius of curvature) n is the refractive index of the material used R1 is the radius of curvature of sphere 1 R2 is …
