Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

The low power objective of a microscope has a magnification of 4x. If the eyepiece has a magnification of 10x, then what is the total magnification you are using?

A	4x
B	400x
C	40x
D	10x

Explanation:

Detailed explanation-1: -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-2: -To get the total magnification take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X.

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.

Detailed explanation-4: -For example, optical (light) microscopes are usually equipped with four objectives: 4x and 10x are low power objectives; 40x and 100 are powerful ones. The total magnification (received with 10x eyepiece) of less than 400x characterizes the microscope as a low-powered model; more than 400x as a powerful one.
