To find the position of the image formed by a double convex lens, we can follow these steps: ### Step 1: Identify the given values - Refractive index (n) = 1.5 - Radius of curvature (R1 and R2) = 30 cm (for a double convex lens, R1 is positive and R2 is negative) - Object distance (u) = -120 cm (the object distance is taken as negative in lens formula) ### Step 2: Use the lens maker's formula to find the focal length (f) ...
