Magnification,

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

Magnified images are formed on the same side as the object. The image distance is thus positive.

1. What can one say about the image produced by a thin lens that produces a positive magnification?

a. It is real and inverted

b. It is real and erect.

c.It is virtual and inverted.

d. It is virtual and erect.

2. If the diameter of a lens is reduced, what happens to the magnification produced by the lens?

a. It increases

b. It decreases

c. It is unchanged
