To solve the problem, we will follow these steps: ### Step 1: Identify the given values - Radius of curvature \( R_1 = 20 \, \text{cm} \) (for the first surface) - Radius of curvature \( R_2 = -40 \, \text{cm} \) (for the second surface, negative because it is on the opposite side) - Refractive index \( \mu = 1.5 \) - Object distance \( u = -40 \, \text{cm} \) (negative as per the sign convention) ...
