PhysicsEasysingle choice

A convex lens of focal length ' $f$ ' produces a real image ' $n$ ' time the size of the object. The image distance is

Options:

Answer:

Solution:

The image is real and hence inverted. $∴ \frac{v}{u} = - n or u = - \frac{v}{n}$ By lens equation, $\frac{1}{v} - \frac{1}{u} = \frac{1}{f}$ $\frac{1}{v} + \frac{n}{v} = \frac{1}{f} v = f (1 + n)$
