A microscope has a scanning objective ( $4x$ magnification) whose field of view is 3 millimeters ( $\mathrm{mm})$ in diameter. What is the diameter of the field of view of the microscopes' oil immersion objective? Use the formula below to calculate the answer. $\mathrm{FOV}=\text{ Field of View }$ Diameter of FOV $(\mathrm{mm})$ of Objective $\mathrm{N}=$ Diameter of FOV $(\mathrm{mm})$ of $4\times$ Objective $\times \left(\frac{\text{ Magnification of Scanning Objective }}{\text{ Magnification of objective }\mathrm{N}}\right)$ 12 micrometres 1200 micrometres 1.2 micrometres 120 micrometres 0.12 micrometres
