Magnification vs Image Distance
Formula
## Optical Magnification Magnification describes the ratio of image size to object size. ### Formula **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.
Exemplo Resolvido
Image at 15 cm, object at 30 cm.
- 01M = -di / do
- 02M = -15 / 30
- 03M = -0.5
- 04The image is inverted and half the size of the object.
Perguntas Frequentes
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.
