A microscope will have maximum resoving power, if to illuminate the specimen, it uses light of

1. red colour

2. green colour.

3. yellow colour.

4. blue colour.

Solution: blue colour

The resolving power of an instrument refers to its ability to resolve two points that are close together. We know that:

Resolving Power 

And as out of the given lights, blue light has the least wavelength so the Resolving power of a microscope will be maximum when blue light is used to illuminate the specimen.
