" 18.For a convex mirror prove that,"(1)/(v)+(1)/(u)=(1)/(f)

For a convex lens for any image prove that 1/v-1/u=1/f .

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

For a concave mirror, prove that 1/u+1/v=1/f , where u, v and f have their usual meanings.

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 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 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

In case of concave mirror what is the shape of (1)/(u) ~ (1)/(v) graph?
