My question is:
Examine the micrograph of the letter e shown in figure 3.4. This letter is magnified 40x. What is the actual height of the letter?
HERE is figure 3.4
I think I should use one of the calculations HERE, starting at Alternative Procedure 3.3, but I'm so confused. Do I have to measure the diameter of the e as seen in that image, and then use that as Maglow? But then what is the FOVlow and everything else? If I could just understand which is which, I should be able to do it. Thanks!
