Discussion
You are looking at a specimen with a compound microscope. The ocular lens has a magnification of 8X and the objective lens has a magnification of 2X. What is the total magnification ?
Answer: D
The total magnification is 16X.
In a compound microscope the objective forms a magnified image, and the ocular (eyepiece) magnifies that image again, so the two magnifications multiply:
\[ 8 \times 2 = 16 \]
10X adds the two powers instead of multiplying them, and 8X and 2X are the powers of the single lenses on their own.
