Magnification of a compound microscope is not connected to:
Correct answer: A. Numerical aperture
- A. Numerical aperture
- B. Focal length of objective
- C. Focal length of eye piece
- D. Tube length
Explanation
Numerical aperture (NA) is a measure of the ability of the lens in the microscope to gather light and resolve fine details of the specimen. It is related to the angle of light acceptance and the refractive index of the medium between the specimen and the lens. Higher numerical aperture generally results in better resolution and higher quality images, but it does not determine the magnification of the microscope. Other terms given in the options either directly or indirectly determine the magnification of the compound microscope.
