Working principal : A simple microscope is used to obtain small magnifications. It is usally used for study of microscopic algae, fungi and biological specimen.
Light from a light source (mirror) passes through a thin transparent object (Figure 4.2). A biconvex lens magnifies the size of the object to get an enlarged virtual image. The image is viewed from the other side.
