Detailed explanation-1: -Therefore, a 10x eyepiece used with a 40X objective lens, will produce a magnification of 400X. The naked eye can now view the specimen at a magnification 400 times greater and so microscopic details are revealed.
Detailed explanation-2: -If the total magnification of a slide is 400x and the ocular lenses are 10x, we can find the magnifying power of the objective being used by dividing the total magnification of the slide by the magnification of the ocular lens: 400x÷10x=40x 400 x ÷ 10 x = 40 x .
Detailed explanation-3: -Revolving Nosepiece or Turret: This is the part of the microscope that holds two or more objective lenses and can be rotated to easily change power (magnification). Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope. They almost always consist of 4x, 10x, 40x and 100x powers.
