A plano-convex lens of refractive index ($$\mu_1^{\prime}$$ fits exactly into a plano-concave lens of refractive index $$\mu_2$$. Their plane surface are parallel to each other. 'R' is the radius of curvature of the curved surface of the lenses. The focal length of the combination is

$$\frac{\mathrm{R}}{\mu_1-\mu_2}$$

$$\frac{R}{2\left(\mu_1+\mu_2\right)}$$

$$\frac{2 R}{\mu_1-\mu_2}$$

$$\frac{\mathrm{R}}{2\left(\mu_1-\mu_2\right)}$$
