Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which lens is the first magnification step? It always has a magnification of 10X?
A
scanning objective
B
eyepiece
C
low-power objective
D
high-power objective
Explanation: 

Detailed explanation-1: -In common light compound/optical microscopes, the ocular lens magnification is always 10X. The objective lens magnification can be 4X, 10X, 40X, or 100X. The overall magnification of any microscope is readily achieved by multiplying both the objective and the ocular lens magnification.

Detailed explanation-2: -Low Power Objective (10x) The total magnification of a low power objective lens combined with a 10x eyepiece lens is 100x magnification, giving you a closer view of the slide than a scanning objective lens without getting too close for general viewing purposes. Figure 1. Sample objective magnifications.

Detailed explanation-3: -Eyepiece or Ocular is what you look through at the top of the microscope. Typically, standard eyepieces have a magnifying power of 10x.

Detailed explanation-4: -Magnifying power is a measurement of how much bigger an object appears when viewed through a lens or microscope. The “X” inscribed on each eyepiece and lens stands for “times, ” so a 10X lens will make an object appear 10 times bigger than it is.

Detailed explanation-5: -The total magnification is the product of the magnifications of two lens systems. Hence, the microscope which has a 10X objective lens and 10X ocular lens, it would magnify the object by 10 × 10 = 100 times.
