Magnification vs Image Distance

Formule

Magnification describes the ratio of image size to object size.

M = -d_i / d_o = h_i / h_o

Negative M means the image is inverted. M> 1 means the image is enlarged;M < 1 means it is reduced.

Image at 15 cm, object at 30 cm.

What does negative magnification mean?

The image is inverted (flipped upside down) relative to the object. Positive magnification means an upright image.

What magnification does a flat mirror give?

M = +1, meaning the image is the same size and upright, but laterally reversed (left-right swap).

How does a microscope achieve high magnification?

By combining an objective lens (high magnification) with an eyepiece lens (additional magnification). Total magnification is the product of both.
