Q: If a microscope has a field diameter of 4 mm at 40x magnification, what is the field diameter at 400x magnification?

$$\frac{4 \text{ mm} \times 40}{400} = 0.4 \text{ mm}$$

Q: A researcher observes that increasing the magnification on a microscope decreases the field of view. Which formula best explains this relationship?

$$\text{Field of View} \propto \frac{1}{\text{Magnification}}$$
