the main part of the microscope that is used to see and denlarge specimens what do you call this part?

I believe you are asking about the objective lens or eyepiece.

Explanation:

Objective lenses are used to magnify objects enough for you to see them in great detail

Eyepiece/Ocular is what you look through at the top of the microscope.

A tube connects the eyepiece lens to objective lenses, which enhance the magnification power of the eyepiece lens. Both the eyepiece and the objective lens contribute to the magnification of the object.

The eyepiece lens usually magnifies 10x, and a typical objective lens magnifies 40x.

logT=1.5 > logT=¬1.5 > T= 10^(¬1.5)=0.316 > %T= (T)(100)=31.6 If we use this answer as a basis, we can see that the absorbance measurements >1 have the possibility of not being accurate. This is because the percent transmittance will be close to 100.
