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: -Ordinary light microscopes are equipped with three objective lenses (5 ×/10 ×, 40 ×, and 90/100 ×), and two ocular (5 ×, 10 ×) lenses.

Detailed explanation-3: -Enlargement or magnification of a specimen is the function of a two-lens system; the ocular lens is found in the eyepiece, and the objective lens is situated in a revolving nose-piece. These lenses are separated by the body tube.

Detailed explanation-4: -Compound microscopes have two magnifying lenses, the objective lens and the ocular (eyepiece) lens. The function of the ocular lens is to magnify an image ten times (10X).

Detailed explanation-5: -A simple microscope is a magnifying instrument that uses only one lens to magnify objects.
