Purpose: Demonstrate how the optics of a microscope produces a magnified image.
Description: A mirror mounted under the microscope stand is placed to light up the subject. Light bounces off the mirror, passes through and around the subject (mounted firmly to a microscope slide), and into the objective lenses. The objective lens of a microscope is small and spherical, with a short focal length. It brings the image of the object into focus at a short distance within the microscope's tube. The image is then magnified by a second lens, called an ocular lens or eyepiece.
