We will also introduce the term principal axis and see the need for it.  Mahesh Shenoy video https://cdn.kastatic.org/googleusercontent/Mw5fCu2i7a7t7ZW3oQnnUucKu8_n8DGS0ZO3J7uRgDbQSZbrtjuSMgY2ew69NU2XIrRuATkeFsBlEKCk7-POGQ2x0A Spherical mirrors, radius of curvature & focal length In this video, we will introduce the terms radius of curvature, and see its connection with focal length.
