To solve the problem step by step, we will follow the reasoning and calculations outlined in the video transcript. ### Step 1: Understand the Setup We have a convex lens and a convex mirror placed coaxially. The radius of curvature (R) of the convex mirror is given as 30 cm. The distance between the lens and the mirror is 40 cm. An object is placed 35 cm away from the lens, and the final image coincides with the object. ### Step 2: Determine the Focal Length of the Mirror The focal length (f) of a convex mirror is given by the formula: \[ f = \frac{R}{2} \] ...
