Problem
If an object is placed a distance p from a thin glass lens (index of refraction ns), we can see its image on a screen that is placed a distance d from the lens. Without altering any distances, we immerse this system into a liquid (index of refraction n). Under what conditions can we still observe the object's image on the screen, and how far from lens would this image be?
