1. a) If a drawing is 50 mm and the actual size of the object is 20 µm, what is the drawing magnification? b) For this drawing magnification, how long would a scale bar have to be to represent a distance of 10 um? 2. Suppose you measure the low power field of view with a ruler and it is 4 mm. If high power is 10X more magnification than low power, what will the field of view be? 3. What reagent would have had to been added to allow viewing at 1000x magnification? Explain why in optical terms. 4. On the third (bottom) diagram hundreds of dark blue particles are seen. What microorganisms do these particles represent? What is their likely source? 1. a) If a drawing is 50 mm and the actual size of the object is 20 µm, what is the drawing magnification? b) For this drawing magnification, how long would a scale bar have to be to represent a distance of 10 um? 2.
