To find the relationship between focal length (f) and radius of curvature (R), we can follow these steps:1. Understanding the Concepts: - A lens or mirror can be thought of as a part of a sphere. The radius of curvature (R)
Why the focal length of a spherical mirror has a smaller magnitude than that of its radius of curvature?Focal Length:In optics, focal length represents the distance between the centre of the mirror or lens (which is also known as a pole) and the focal poi...
