Detailed explanation-1: -High Power Objective Lens (40x) The high-powered objective lens (also called “high dry” lens) is ideal for observing fine details within a specimen sample.
Detailed explanation-2: -Answer: The 4x or 5x has a red ring; the 10x yellow; the 20x green; the 40x or 50x or 60x blue; the 100x white. These rings make it easier to visually identify the magnification of the objective; the colors are standard for most manufacturers.
Detailed explanation-3: -To get the total magnification level you must multiply the magnification of the ocular lens by the magnification of the objective lens. So, if you are viewing your slide under the 40x objective lens you would multiply that by the 10x of the ocular lens for a total magnification of 400x.
