In this article we will discuss about the design of a compound microscope with the help of diagram. Compound microscope is a very useful optical instrument. It gives a high magnification necessary for working out the details of minute organisms and also for studying the internal structures of plants and animals. The instrument rests on a horse-shoe-shaped base (foot) with [...]
