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

The focal length of a mirror is give by (1)/(f)=(1)/(u)+(1)/(v) , where 'u' represents object distance, 'v' image distance and 'f' local length. The maximum relative error is

The focal length of a mirror is give by (1)/(f)=(1)/(u)+(1)/(v) , where 'u' represents object distance, 'v' image distance and 'f' local length. The maximum relative error is

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

If 'f' is the focal length of a lens then prove uv=f^2 . U and V represent object and image distances from focus respectively.

If (1)/(f)=(1)/(u)+(1)/(v) , then make v as the subject of the formula.
