Answer:

The first objective lens that someone should first use to view a slide is the   4x magnification objective lens.

Explanation:

  • This is because the  4x magnification objective lens has got the lowest magnification power.
  • This in turn means that it has the highest field of view.
  • This in turn makes it easier to locate the specimen first before switching to lenses with higher magnification power for focus after finding the location of the specimen.
