In an example, we found that when a convex meniscus lens is flipped front to back, it remains a converging lens with the same focal length. Is this true of all lenses, or is it a particular feature of the convex meniscus lens? Starting with the lens maker’s equation, determine which variables change when a lens is flipped and whether the results are true for all lenses.
