Answer:

1 =1 +1

f. v u

Explanation:

f is the focal length

v is the image distance

u is the object distance

1/f = 1/v + 1/u

The above formula gives us the relation between 'f' 'v' & 'u', Where :

              f = focal length

              v = image distance

              u = object distance

This formula not only used for concave mirror, but also for convex mirror.
