Detailed explanation-1: -The total magnification is determined by multiplying the magnification of the ocular and objective lenses.
Detailed explanation-2: -To calculate the total magnification of a microscope, simply multiply the power of the ocular lens by the power of the objective lens. For example, if the ocular lens is 5X and the objective lens is 12X, the total magnification would be 5 x 12 or 60X.
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: -A scanning objective lens provides the lowest magnification power of all objective lenses. 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.
