Lens and Mirror: Image Formation and Ray Tracing

This lecture discusses the formation of images by a converging light beam passing through a diverging lens, reflecting off a flat mirror, and passing back through the lens in reverse. The instructor explains how to determine the location of the resulting image using the given focal length of the lens, the separation distance between the lens and the mirror, and the initial convergence point of the light beam. Through detailed ray tracing analysis, the lecture demonstrates the different scenarios that can occur based on the positioning of the lens, mirror, and focal point, providing a comprehensive understanding of image formation in optical systems.
