Vedclass · Answer

(B) The resolving power $(RP)$ of a compound microscope is given by the formula $RP = \frac{2n \sin \beta}{1.22 \lambda}$.From this expression,it is clear that the resolving power is inversely proportional to the wavelength of the light used,i.e.,$RP \propto \frac{1}{\lambda}$.Since the wavelength of violet light $(\lambda_{	ext{violet}})$ is smaller than the wavelength of red light $(\lambda_{	ext{red}})$,using violet light will result in a higher resolving power.Therefore,the resolving power is maximum when violet light is used to illuminate the object.
