Given a thin convex lens (refractive index $\displaystyle \mu_2$ ), kept in a liquid (refractive index $\displaystyle \mu_1, \mu_1<\mu_2$ ) having radii of curvatures $\displaystyle \left|\mathrm{R}_1\right|$ and $\displaystyle \left|\mathrm{R}_2\right|$. Its second surface is silver polished. Where should an object be placed on the optic axis so that a real and inverted image is formed at the same place?
