Detailed explanation-1: -Typically, a compound microscope is used for viewing samples at high magnification (40-1000x), which is achieved by the combined effect of two sets of lenses: the ocular lens (in the eyepiece) and the objective lenses (close to the sample).
Detailed explanation-2: -In a compound microscope two lenses are present they are-occular lens which is close to eye piece and objective lens which is close to the sample.
Detailed explanation-3: -A compound microscope has two lenses. Each lens in a compound microscope serves an important purpose, and together they allow scientists to examine a specimen with much more clarity than they could with a single lens.
Detailed explanation-4: -There are two sets of lenses in both the compound microscope and the dissecting microscope (also called the stereo microscope). Both of these microscopes have an objective lens, which is closer to the object, and an eyepiece, which is the lens you look through.
Detailed explanation-5: -A compound microscope uses multiple lenses to magnify an image for an observer. It is made of two convex lenses . The first, the ocular lens, is close to the eye and the other lens is objective lens. Both the lenses are of different focal length because uses of both are different.
