Question

If the area of a circle is equal to sum of the areas of two circles of diameters 10 cm and 24 cm, calculate the diameter of the larger circle (in cm).​

Answer 1

Radius of curvature of the convex surface is given as 10 cm and the radius of curvature of the plane surface is infinity. We are also given the refractive index $\mu =1.5$. Therefore, the focal length of the lens is $20cm$.
