उत्तर
The resolving power of a microscope is given by the relation
`"RP" = 1/d_"min" = (2"n" sin beta)/(1.22 lambda)`
(i) When the diameter of the objective lens is decreased β decreases so resolving power decreases.
(ii) When the wavelength of the incident light is increased resolving power decreases.
