Inside Body Tube)
Bending Light: The objective (bottom) convex lens magnifies and focuses (bends) the image inside the body tube and the ocular convex (top) lens of a microscope magnifies it (again).

The body tube holds the objective lenses and the ocular lens at the proper distance
The Nose Piece holds the objective lenses and can be turned to increase the magnification
The Objective Lenses increase magnification (usually from 10x to 40x)
