To solve the problem, we will follow these steps: ### Step 1: Understand the Problem We have a combination of two lenses where the resultant focal length is -60 cm (since it diverges the rays). One of the lenses is convex with a focal length of +60 cm. We need to find the focal length and power of the other lens. ### Step 2: Assign Variables Let: - \( f \) = resultant focal length of the combination = -60 cm = -0.6 m ...
