WebSep 12, 2024 · It shows that the focal length of a thin lens depends only of the radii of curvature and the index of refraction of the lens and that of the surrounding medium. For a lens in air, n1 = 1.0 and n2 ≡ n , so the lens maker’s equation reduces to. 1 f = (n − 1)( 1 … WebA diverging lens of focal length \( 9 \mathrm{~cm} \) is 25 \( \mathrm{cm} \) to the right of the converging lens. Find the position and magnification of the final image. \[ \mathrm{cm} \] Question: An object is placed \( 17 \mathrm{~cm} \) to the left of a converging lens of focal length \( 26 \mathrm{~cm} \). A diverging lens of focal length ...
