Sudha finds out that the sharp image of the window pane of her science laboratory is formed at a distance of `15 cm` from the lens. She now tries to focus the building visible to her outside the window instead of the window pane without disturbing the lens. In which direction will she move the screen to obtain a sharp image of the building ? What is the approximate focal length of this lens ?

To solve the problem, we will analyze the situation step by step. ### Step 1: Understanding the Image Formation Sudha has found that a sharp image of the window pane is formed at a distance of 15 cm from the lens. This means that the object (the window pane) is located at a position where the lens can focus light to create a clear image. **Hint:** Remember that the distance at which the image is formed is related to the position of the object and the focal length of the lens. ### Step 2: Identifying the Type of Lens ...
