Lens Maker’s Formula — Single vs Multiple Surfaces & Power Addition | Topic 50 | Ray Optics | SSP

In this lecture, Sandeep Sir explains the Lens Maker’s Formula by connecting the behaviour of a single refracting surface with a lens made up of multiple surfaces. The session covers how the power of individual refracting surfaces contributes to the total power of a lens, and how refractive index and radii of curvature determine the focal length. Students will understand the logic behind power addition, the transition from surface power to lens power, and the derivation of the Lens Maker’s Formula. This lecture helps build a strong conceptual foundation in lenses, refraction, optical power, and Ray Optics for JEE and other competitive examinations.
