Refraction at Spherical Interface

This lecture covers the refraction at a spherical interface, discussing the relationship between the angles of incidence and refraction, the refractive indices of the media involved, and the conventions for sign determination. It also explores the impact of different parameters on the refraction process, such as the radius of curvature and the independence of the distance. The lecture emphasizes the application of the refraction laws in various scenarios and provides a detailed analysis of the calculations involved.
