derivation of magnification formula of compound microscope
Answers
Compound microscope is made up of two convex lenses. The convex lens that is close to the object is known as objective lens and the lens placed near to the eye is known as eye piece.
Objective lens has small focal length and small aperture because for small focal length it is necessary to have small aperture.
Eye piece has the same behavior as that of simple microscope.
While using compound microscope, object should be placed slightly outside the focus.
Consider an object AB is placed on the principle axis at a distance slight away from the focus of the objective lens. We consider two rays from the object, first ray is incident parallel to the principle axis and passes through focus after refraction while the second ray is directed towards the optical center and it passes without deviation.
