What is f in mirror formula (1)/(u)+(1)/(v)=(1)/(f) ?

The focal length of a mirror is given by (1)/(v)-(1)/(u)=(2)/(f) . If equal errors alpha are made in measuring u and v then relative error in f is

The focal length of a mirror is given by (1)/(v)-(1)/(u)=(2)/(f). If equal errors alpha are made inmeasuring u and v. Then relative error in f is

The focal f to a mirror is given by (1)/(f) = (1)/(u) + (1)/(v) where u and v represent object and image distance respectively then
