The formula to find the radius of curvature is 2f or 2 x focal length.
- The Radius of curvature of a mirror or a lens is defined as the two times of the focal length of that mirror or lens.
- It is the distance between the pole (P) and the center of curvature(C).
- Its mathematical formula is:
Radius of curvature = 2 x focal legth (f)
R = 2 x f
- The Focal length (f) of a mirror or lens is the distance between the pole and its focus (F).
