Move over, Tatooine

The article focuses on the phenomenon of multiple reflections of sunlight observed in glass globes, specifically a hollow glass globe and a smaller solid glass globe. The author describes the process of observing and sketching the ray diagrams for the reflections, noting that different angles of incidence produce various reflection patterns. The article poses questions regarding the deviation angles of rays after multiple internal reflections in both hollow and solid spheres, inviting readers to explore the differences in behavior based on the refractive index of the materials. Additionally, it encourages engagement with Fermi Questions, which involve estimation techniques for scientific inquiries.

Abstract

The article focuses on the phenomenon of multiple reflections of sunlight observed in glass globes, specifically a hollow glass globe and a smaller solid glass globe. The author describes the process of observing and sketching the ray diagrams for the reflections, noting that different angles of incidence produce various reflection patterns. The article poses questions regarding the deviation angles of rays after multiple internal reflections in both hollow and solid spheres, inviting readers to explore the differences in behavior based on the refractive index of the materials. Additionally, it encourages engagement with Fermi Questions, which involve estimation techniques for scientific inquiries.
