Focal length of spherical mirror
WebSpherical mirrors, radius of curvature & focal length Google Classroom About Transcript In this video, we will introduce the terms radius of curvature, and see its connection with focal length. We will also introduce the term principal axis and see the need for it. Created by Mahesh Shenoy. Sort by: Top Voted Questions Tips & Thanks WebOr FC = BF = PF. Or PC = PF + FC = PF + PF. Or R = 2 PF = 2f. Or f = R/2. This kind of relation can be applied for convex mirrors too. In this relation, the aperture of the mirror is assumed to be small. Radius of curvature is …

WebAug 15, 2024 · Using the law of reflection and some simple trigonometry, it can be shown that the focal length is half the radius of curvature, or (11.7.1) f = R 2, where R is the radius of curvature of a spherical mirror. The smaller the radius of curvature, the smaller the focal length and, thus, the more powerful the mirror. smart bill of ladingWebFor a single spherical mirror, the focal length will always be half the radius of curvature. Note that rays which are both parallel and near to the principal axis are reflected through the focus.
