radius of curvature of two faces of double convex lens are 10cm ,15cm and it focal length is 12cm .then determine the refractive index of the lens
Added by Alexis H.
Step 1
We know that the lens maker's formula is given by: \(\frac{1}{f} = (n - 1)(\frac{1}{R_1} - \frac{1}{R_2})\) where f is the focal length, n is the refractive index, and R1 and R2 are the radii of curvature of the two faces of the lens. Show more…

If the focal length of a double convex lens is 12 cm and radii of curvatures of faces are 10 cm and 15 cm respectively, what is the refractive index of the lens?
Madhur L.
The focal length of a convex lens is 10 cm and its refractive index is 1.5. If the radius of curvature of one surface is 7.5 cm, the radius of curvature of the second surface will be
