Considering the data in the question, the focal length of the objective lens that will give a total magnification of 200x is <u>0.8cm focal length.</u>
The whole question is:
You are using a microscope with a 10x eyepiece. What focal length of the objective lens will give a total magnification of 200x? Assume a length L = 160mm.
<h3>How was the answer derived?</h3>
Given that total magnification is 200
And the Assume length is 160
Since we used a microscope with a 10x eyepiece, the magnification would be divided by 10.
=> 200 ÷ 10 = 20.
Also, the focal length is measured in centimeters or meters; we would change the millimeters of focal length to centimeters. Therefore, we have 160 ÷ 10 = 16
The formula for the focal length of the objective lens = assumed length ÷ total magnification.
=> 16 ÷ 20 = 0.8cm.
Hence, in this case, it is concluded that the correct answer is "0.8cm."

It is important for chemists to study changes in the world at a submicroscopic level because it enable chemists to understand difficult concepts that they cannot normally see.
Given that the chemists are required to study the changes in the world at a submicroscopic level.
We are required to tell the reason why the chemists are required to study changes in the world at a submicroscopic level.
The submicroscopic level of representation is basically particulate theory of matter, is used to explain the macroscopic phenomena in terms of the movement of particles such as electrons, molecules, and atoms.
The chemists are required to study changes in the world at submicroscopic level because it helps the chemists to understand different concepts at lower level.
Hence it is important for chemists to study changes in the world at a submicroscopic level because it enable chemists to understand difficult concepts that they cannot normally see.
