The amount the lens magnifies your vision by.
For example "x20" means "times twenty" as in being able to see the object being examined 20 times larger.
Not at all as both times the biologist is using the "X" lens.
A microscope lens number followed by an "x" is referred to as the magnification power of that lens. It indicates how much larger the lens can make an object appear compared to its actual size. For example, a lens with a magnification of 10x enlarges the object by ten times. This designation helps users select the appropriate lens for viewing specimens at different levels of detail.
The upper lens in a microscope is called the eyepiece or ocular lens. It is the lens through which the viewer looks to observe the magnified specimen on the microscope slide.
The total magnification of a compound microscope is calculated by multiplying the magnification of the objective lens by the magnification of the eyepiece. So, total magnification = magnification of objective lens x magnification of eyepiece.
A simple microscope has only one lens.
The objective lens
10 x 5 = 50 the magnification of microscope is 50
The low power objective lens on a microscope is also known as the scanning lens.
a compound microscope has two or more lens while a simple microscope has only one lens
To change the magnification lens on a microscope, first, ensure that the microscope is turned off. Then, gently unscrew or detach the existing lens from the microscope. Carefully insert the new lens in its place and secure it in position. Finally, test the new lens by turning on the microscope and adjusting the focus as needed.

lower power= 20 x 10= 200x higher power= 20 x 43= 860x
