Explanation:
Detailed explanation-1: -A compound microscope has multiple lenses: the objective lens (typically 4x, 10x, 40x or 100x) is compounded (multiplied) by the eyepiece lens (typically 10x) to obtain a high magnification of 40x, 100x, 400x and 1000x. Higher magnification is achieved by using two lenses rather than just a single magnifying lens.
Detailed explanation-2: -Therefore, we multiply the ocular objective lens magnification (10x) with the high power objective lens (50x); hence, the total magnification equals 500x.
Detailed explanation-3: -Grades 1-8 typically will buy a monocular compound microscope with 3 objective lenses: 4x, 10x, 40x for maximum total magnification of 400x.
