A magnifying glass is a simple microscope.
Explanation:
light microscope consisting of one converging lens that's accustomed manufacture an enlarged image.
The ocular lens (the one nighest to your eye) magnifies the image from the target lens, rather a sort of a hand glass. On some microscopes, you'll move the ocular up and down by turning a wheel. this provides you fine management or "fine-tuning" of the main target.
