PRACTICE PROBLEMS AND REVIEW QUESTIONS 1. What is the total magnification of an object if the ocular lens magnification is 20x and the objective lens magnification is 45x? 2. Which objective lens is in place if the object you are viewing is magnified 1000x assuming an ocular lens magnification of 10x? 3. What is the diameter of the field of view (DFV) of a 1000x objective lens if the DFV of a 400x objective lens is 500 µ? Express your answer in mm. 4. What is the DFV of a 40x objective lens if the DFV of a 10x objective lens is 3 mm? Express your answer in µ. 5. When viewing an organism using the 40x objective lens from question 4, you estimate 6 organisms could fit across the DFV if they were laid end-to-end and 20 could fit is stacked side by-side. What is the length and width of this organism (in microns)? 6. What is the DFV of a 25x objective lens if the DFV of a 100x objective lens is 1.5 mm? 7. Using the 100x objective lens from question 6, you estimate 12 organisms could fit across the DFV if they were laid end-to-end and 30 could fit is stacked side-by-side. What is the length and width of this organism (in microns)? 8. What is the magnification of an objective lens with a DFV or 0.8 mm if the DFV of a 100x objective lens is 2 mm?
