SUMMARY
The discussion focuses on calculating the thickness of a film with an index of refraction of 1.7, applied to a glass lens with an index of refraction of 1.6, to achieve strong reflection for 610 nm light. The problem involves understanding thin film interference, specifically how varying the film thickness affects the reflection intensity. The initial condition requires finding the minimum thickness that produces a strong reflection, followed by determining the thickness at which strong reflection occurs again as the film is thickened.
