To solve the problem step-by-step, we will first draw a labeled ray diagram for the formation of an image by a convex lens and then calculate the size of the image formed. ### Step 1: Identify the Given Values - Focal length of the convex lens (f) = +15 cm (positive for convex lens) - Object distance (u) = -25 cm (negative as per sign convention) - Height of the object (h1) = 4 cm ### Step 2: Use the Lens Formula ...
