A convex mirror of focal length f forms an image which is 1/n times the object. The distance of the object from the mirror is : |
(n-1) f \(\frac{n-1}{n}\) f (n+1) f \(\frac{n+1}{n}\) f |
(n-1) f |
$ m = \frac{1}{n} = -\frac{v}{-u}$ $ v = \frac{u}{n}$ Mirror Equation $\frac{1}{v} + \frac{1}{u} = \frac{1}{f}$ $ \frac{n}{u} + \frac{1}{-u} = \frac{1}{f}$ $\Rightarrow u = (n - 1)f$ |
