Challenge Problems
Push your limits with advanced challenges
Analyze a scenario where an object is moved closer to a convex lens. Predict how the image distance changes and illustrate with a ray diagram.
💡 Hint: Remember the rules of ray diagrams as you draw.
A concave lens has a focal length of -5 cm. Determine the image location for an object located 10 cm from the lens using the lens formula.
💡 Hint: Use the lens formula carefully with proper sign conventions.
