Focal length formula mirror
WebJan 25, 2024 · The focal length \ (f.\) of the mirror is related to its radius of curvature \ (\left ( R \right)\) by the relation: \ (f = \frac {R} {2}\) Thus, the mirror equation is given by the relation: \ (\frac {1} {v} + \frac {1} {u} = … WebThe distance between the pole and the focus of the mirror is called the focal length of the mirror. Hence, f= 2R Note: Focal length of the mirror is a measure of power of the mirror. formula Prove that focal length is half of radius of curvature in spherical mirrors Consider a Concave mirror shown in the figure above.
