Radius of curvature from focal length

WebJan 25, 2024 · Each lens has two radii of curvature. With the change in the shape of a lens, there will be a change in the radius of curvature. Focal length: All the rays coming parallel to the principal axis of a lens, after refraction, either converge or appear to diverge from a point on the principal axis called the focus or principal focus. WebThe focal length decreases in both cases: when the radius of curvature and the refractive index increase. The focal length increases when the radius of curvature increases; it decreases when the refractive index increases. The focal length decreases when the radius of curvature increases; it increases in when the refractive index increases.
