To solve the problem of finding the angular magnification achieved due to the converging lens, we can follow these steps: ### Step 1: Understand the Setup We have a converging lens (convex lens) with a focal length (F) of 50 cm. The image of the moon, which is considered to be at an infinite distance, is focused on a plane screen. The image formed is then viewed by an unaided eye from a distance (D) of 25 cm. ### Step 2: Identify the Angles Let: - \( \alpha \) be the angle subtended by the moon at the lens. ...
