A spherical surface separates two media of refractive indices 1 and 1.5 as shown in figure. Distance of the image of an object ‘O’, is (C is the center of curvature of the spherical surface and R is the radius of curvature)

1. 0.4 m left to the spherical surface
2. 0.24 m left to the spherical surface
3. 0.24 m right to the spherical surface
4. 0.4 m right to the spherical surface

Correct answer: 0.4 m left to the spherical surface
