A schematic cross-section of a biconvex lens submerged in liquid. The horizontal principal axis passes through the center of the lens. To the left of the lens, a vertical arrow pointing upward represents an object at distance d_o = 30 cm, labeled Object. The surrounding liquid is shaded lightly and labeled n_L = 1.80. The lens material is labeled n_g = 1.50. Ticks marked along the axis indicate the relative placement of points. No other labels, lines, text, or axes appear.
A biconvex glass lens submerged in a high-refractive-index liquid.
A thin biconvex glass lens with refractive index \(n_g = 1.50\) has a focal length of \(+20\text{ cm}\) in air. The lens is placed in a transparent liquid with refractive index \(n_L = 1.80\). An object is positioned in the liquid at a distance of \(30\text{ cm}\) in front of the lens.
