In a compound microscope, the objective lens forms an image that is
Correct answer: B. real, inverted and magnified, which the eyepiece then magnifies further
- 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.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
