SUMMARY
The discussion centers on the application of Newton's ring formula, specifically the equation 2t=nλ, where t represents the thickness of the air film, n is the number of rings counted, and λ is the wavelength of light. The participant asserts that the correct diagram for this scenario involves vertical light paths, but questions the impact of the curved surface on the incident and reflected angles. They clarify that when two glass surfaces are in contact, no reflection occurs, which implies an absence of an air gap.
