Physics q239

239As shown in figure, a liquid of refractive index n₂ is poured onto the concave surface of concavo-convex lens. R₁ and R₂ are the radii of curvature of convex and concave surfaces of the lens respectively and R₁ = 2R₂· The refractive index of material of lens is n₁. For which combination of n₁ and n₂, the whole system behaves as a diverging lens
