Focal length and refractive index relation
WebThe lens’s focal length depends upon the refractive index of the material of the lens and the radii of curvatures of the two surfaces. The derivation of lens maker formula is provided here so that aspirants can understand … 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.
