Problem 35.2: Hidden lenses, mixed sources
Please wait for the animation to completely load.
Four regions are hidden by curtains. The light sources are dragable. The arrow represents an object, and the fainter arrow represents its image (position is given in meters).
- What is behind each curtain?
- Rank the objects in terms of their focal lengths, from smallest to largest (most negative to most positive).
