A point source, in air, is placed at a distance of 6 cm in front of a convex spherical surface ( n =1 · 5 and radius of curvature =24 cm ). Find the…

\[\begin{aligned} & \frac{\mathrm{n}_{2}-\mathrm{n}_{1}}{R}=\frac{\mathrm{n}_{2}}{\mathrm{v}}-\frac{\mathrm{n}_{1}}{u} \\ & \frac{1.5-1.0}{24}=\frac{1.5}{\mathrm{v}}-\frac{1.0}{-6} \end{aligned} \] After solving \[\mathrm{v}=\frac{-72}{7} \approx-10.28 \mathrm{~cm} \] Nature: Virtual
