Lecture
This lecture focuses on solving a complex lens system problem involving a converging lens and a diverging lens. The instructor explains how to find the location of the image formed by the system by analyzing the path of light rays through each lens. Through geometric constructions and lens formulas, the lecture demonstrates the step-by-step process of determining the final image position. By considering the focal lengths and distances between the lenses, the instructor guides the audience in understanding the image formation in such optical systems.
