The diameter of the objective lens of microscope makes an angle $\displaystyle \beta$ at the focus of the microscope. Further, the medium between the object and the lens is an oil of refractive index n . Then the resolving power of the microscope.
Official answer
(3)
Increases with increasing value of $\displaystyle \mathrm{n} \sin 2 \beta$
