To calculate the magnifying power of a simple microscope consisting of two lenses in contact, we can follow these steps:
### Step 1: Calculate the Focal Length of Each Lens
The power \( P \) of a lens is related to its focal length \( f \) (in meters) by the formula:
\[
P = \frac{1}{f}
\]
Thus, the focal length can be calculated as:
...
