The resolving power of a microscope depends upon all of the following except:
(A) Size of the apeure (B) Focal length of the eyepiece (C) Thickness of the film (D) Wavelength of light source used
(C) Ans: C. Thickness of the film(Ref Bancroft Theory & Practice of Histochemical Techniques/p45-47).Resolving power of microscope:Microscope specific.Inversely distance between two objects that can be resolved.Doesn't depend on specimen nature or thickness.According to Abbe's Criterion.
