To find the calibration factor, we need to determine the actual length represented by one division of the eyepiece micrometer. This is done by comparing the eyepiece micrometer to a stage micrometer, which has known divisions. Step 1: Determine the value of one small division on a standard stage micrometer. A standard stage micrometer has divisions where each small division is 0.01 \, mm. Step 2: Convert the value of one small stage micrometer division to microns. Since 1 \, mm = 1000 \, , 0.01 \, mm = 0.01 × 1000 \, = 10 \, Step 3: Calculate the total length represented by the coinciding stage micrometer divisions. The problem states that 20 small stage micrometer divisions coincided. Total length = 20 \, divisions × 10 \, /division = 200 \, Step 4: Calculate the calibration factor for one eyepiece micrometer division. The problem states that 80 small eyepiece micrometer divisions coincided with the 20 small stage micrometer divisions. So, 80 eyepiece divisions = 200 \, . The calibration factor is the value of one eyepiece division: Calibration Factor = Total length of stage micrometer divisionsNumber of coinciding eyepiece micrometer divisions Calibration Factor = 200 \, 80 Calibration Factor = (20)/(8) \, Calibration Factor = 2.5 \, The correct option is 2.5. 2.5 3 done, 2 left today.
