The eyepiece lens of a compound microscope acts essentially a low power (x10 or so) magnifier of the real image created by the objective lens.
The magnification of the objective lens is 10x. The magnification of the scanning lens is 4x. Therefore if you are viewing an object under scanning power, the total magnification is 40x.

magnification of the eyepiece X magnification of the lens (depends on which one you choose)
The objective lens in a microscope helps to magnify the object being viewed on the slide. The objective lens can be rotated to change the magnification of the lens and yield a different view.
The scanning power objective relates to the objective lens. Most microscopes provide two or more objective lenses to give a choice of magnification power. Some also include an oil immersion lens for even greater magnification.
On each lens of a Microscope there is a marking that states the magnification power.
the power of the ocular lens multiplied by the magnification of the objective lens
The power of a light microscope can be determined by multiplying the magnification power of the eyepiece by the magnification power of the current lens. Ex. (10x) by (40x) results in in a 400x magnification.
In a light microscope magnification is varied by using different lenses to refract the light. In an electron microscope magnification is varied by altering the configurations of magnetic fields to bend the electron beam.
To determine the total magnification of a microscope you multiply the magnification power of the objectives lens (indicated as x10) by that of the eye piece.
Microscopes vary in power. You can determine total magnification by the eyepiece and the lens.
The magnification of the objective lens is 10x. The magnification of the scanning lens is 4x. Therefore if you are viewing an object under scanning power, the total magnification is 40x.
Multiply the magnification or power of the objective lens times the power of the eyepiece and it equals the total magnification
20x objective
The lower power objective is the lens on the microscope that gives you the lowest magnification. The exact magnification is 40x
magnification= ocular power *objective power=10X*60X
