To solve the problem, we will use the lens maker's formula and the information provided in the question. ### Step-by-Step Solution: 1. **Understand the Given Information:** - The refractive index of the lens (μ) = 1.5 - The focal length (f) = 5 cm (since the lens renders parallel rays from a distant source) - The radii of curvature are in the ratio of 1:2. Let R1 = R and R2 = 2R. ...
