If ocular lens is 10x and objective is 30x, what is the total magnification?
A
30x
B
300x
C
3000x
D
10x
Explanation: 

Detailed explanation-1: -Multiplying the magnification of each lens yields the overall magnification of the microscope. With a 10x ocular and a 30x objective, the microscope’s total magnification is 300x.

Detailed explanation-2: -The total magnification is the magnification of the ocular lens (10) multiplied by the objective lens (100). If we multiply 100 x 10 = 1, 000. This is noted as the total magnification is 1000x, or 1000 times the size of the specimen.

Detailed explanation-3: -In this case, the total magnification of a microscope is equal to the magnification of the objective ocular lens multiplied by the high-power objective lens. Therefore, we multiply the ocular objective lens magnification (10x) with the high power objective lens (50x); hence, the total magnification equals 500x.

Detailed explanation-4: -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.
