Move over, Tatooine: Solutions for Fermi Questions, January 2026

The article focuses on the optical phenomena observed in glass globes, specifically the multiple reflections of sunlight in both hollow and solid glass spheres. The author describes an experiment conducted in Norfolk, Virginia, where different ray paths of sunlight were sketched as they exited a hollow glass globe, illustrating the effects of reflection. The article also includes mathematical equations to analyze the deviation angles of rays after multiple internal reflections in both hollow and solid spheres, concluding that these angles differ unless the refractive index of the solid sphere is equal to one. The observations highlight the complexities of light behavior in different glass structures.
