PATHOLOGY

Detailed explanation-1: -Therefore, an objective lens of 4x will give you a total magnification of 40x in this case.

Detailed explanation-2: -4x is a common magnification for scanning objectives and, when combined with the magnification power of a 10x eyepiece lens, a 4x scanning objective lens gives a total magnification of 40x.

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.

Detailed explanation-4: -Therefore, we multiply the ocular objective lens magnification (10x) with the high power objective lens (50x); hence, the total magnification equals 500x.

Detailed explanation-5: -Grades 1-8 typically will buy a monocular compound microscope with 3 objective lenses: 4x, 10x, 40x for maximum total magnification of 400x.
