In a compound microscope, the objective lens forms an image that is
- A. virtual and diminished
- B. real, inverted and magnified, which the eyepiece then magnifies further
- C. real and diminished
- D. at infinity
Explanation
The specimen sits just beyond the objective's focal point, so the objective produces a real magnified image inside the tube, and the eyepiece acts as a magnifying glass on that image. The total magnification is the product of the two, which is why a 40 times objective with a 10 times eyepiece gives 400 times. Both lenses are converging and of short focal length.
