Magnification¶
Using a microscope, you can take a closer look at small objects, however you may want to know the size of the image, or the magnification should you not know it.
Equation¶
\[
magnification = \frac{size\;of\;image}{size\;of\;real\;object}
\]
Example¶
For example, take a magnification of 3x, and a size of image of 6mm - what is the size of the real object?
\[
\begin{align}
magnification & = \frac{size\;of\;image}{size\;of\;real\;object} \\
size\;of\;real\;object * magnification & = size\;of\;image \\
size\;of\;real\;object & = \frac{size\;of\;image}{magnification} \\
& = \frac{6}{3} \\
& = 2mm
\end{align}
\]
Using a table¶
| Size of image (mm) | Magnification | Size of real object (mm) |
|---|---|---|
| 5 | 50 | 0.125 |
| 10 | 1000 | 0.01 |
| 12 | 60 | 0.2 |
| 8 | 200 | 0.04 |
| 15 | 500 | 0.03 |
