Vedclass · Answer

(A) For a spherical mirror,the relationship between focal length $f$ and radius of curvature $R$ is given by $f = \frac{R}{2}$.For a convex mirror,the focus $F$ and the center of curvature $C$ are located behind the mirror.According to the sign convention,distances measured in the direction of incident light (behind the mirror) are taken as positive.Therefore,for a convex mirror,both $f$ and $R$ are positive.Thus,the relationship is $f = +\frac{R}{2}$.

The focal length $f$ is related to the radius of curvature $R$ of a spherical convex mirror by
