Answer: A microscope is an instrument that produces a clear magnified image of an object viewed through it. A microscope must be able not only to magnify objects sufficiently but also to resolve, or separate, the fine details of the object that are of interest to the viewer. In the optical microscope visible light rays, reflected from or transmitted by the viewed object, pass through a series of lenses and form an enlarged image of the object. This image is produced at the normal distance of clearest vision, which is about 10 inches, or 25 centimetres, from the eye of the viewer.
