Calculations:
- Stage Scale to Micrometre Conversion: 2 mm = 200 µm (given).
- Field of View to Micrometre Conversion: A field of view of 6 mm is equal to 6 x 103 µm.
- Magnification Calculation: Magnification = (Field of View in µm) / (Stage Scale in µm) = (6 x 103 µm) / (200 µm) = 30x.
- Onion Cell Size Calculation: The stage micrometre scale is calibrated to represent the actual size of the onion cells. Therefore, the actual size of an onion cell is 200 µm.
Answer: The magnification of the objective lens is 30x and the actual size of an onion cell is 200 µm.
