When using a microscope with a X10 ocular and a X40 objective, the total magnification is approximately

• A. 200
• B. 300
• C. 400
• D. 500

Answer: (C)

Total magnification comes from multiplying the magnification of the eyepiece by the magnification of the objective. With a tenfold eyepiece and a fortyfold objective, the product is four hundred times. So the image you see is magnified about four hundred times compared to the naked eye. Remember that increasing magnification narrows the field of view and can affect brightness, so you’ll adjust illumination and focus to see details clearly.
