Question

Resolution power of compound microscope is

• A. 100$\mu m$
• B. 10$\mu m$
• C. 1$\mu m$
• D. 0.25$\mu m$

Answer 1

The correct option is D 0.25$\mu m$

A compound microscope uses two lenses at once to magnify the image of a specimen. The ocular lens is found in the eyepiece while the objective lens is found in the revolving nosepiece. The resolving power is the capacity of an instrument to resolve two points which are close together. The resolving power of a compound microscope is 0.25$\mu$m.
