Vedclass · Answer

(D) The resolving power $(RP)$ of a microscope is given by the formula: $RP = \frac{2n \sin \beta}{\lambda}$, where $n$ is the refractive index of the medium, $\beta$ is the semi-vertical angle, and $\lambda$ is the wavelength of light used.Alternatively, in terms of aperture $(a)$ and focal length $(f)$, $RP \propto \frac{a}{\lambda f}$.$1$. Using an oil immersion objective increases the refractive index $(n)$, which increases the resolving power.$2$. Decreasing the wavelength $(\lambda)$ increases the resolving power.$3$. Decreasing the focal length $(f)$ increases the resolving power.$4$. Decreasing the aperture $(a)$ decreases the resolving power.Therefore, the resolving power cannot be increased by decreasing the aperture.
