Magnification formula is:

$\overline{){\mathbf{m}}{\mathbf{=}}\frac{\mathbf{-}{\mathbf{s}}_{\mathbf{i}}}{{\mathbf{s}}_{\mathbf{o}}}}$

The image is real and inverted.

We have, from the figure, m = - 1.5

Therefore, s_{i} = - ms_{o }= -(-1.5)s_{o} = 1.5s_{o}

A converging lens creates the image shown in:

Is the object distance less than the focal length *f*, between *f* and 2*f*, or greater than 2*f*?
