To solve the problem of finding the position of the image formed by a convex surface separating two media, we will use the formula for refraction at a spherical surface. Here are the steps to find the image position: ### Step 1: Understand the Given Data - Radius of curvature (R) = 40 cm (positive for a convex surface) - Refractive index of medium 1 (μ1) = 4/3 - Refractive index of medium 2 (μ2) = 1.5 - Object distance (U) = -20 cm (negative because it is measured against the direction of the incident light) ...
