principle of microscopy includes 2 important aspects:
1. resolution and resolving power- the resolving power of a microscope is defined as the minimum distance by which 2 points must be separated in order for them to be perceived as 2 separate points rather than a fused image.
2. magnification- Linear (sometimes called lateral or transverse) magnification refers to the ratio of image length to object length measured in planes that are perpendicular to the optical axis. A negative value of linear magnification denotes an inverted image. Longitudinal
magnification denotes the factor by which an image increases in size, as measured along the optical axis.
One advantage of light microscopy over electron microscopy is its relative cheapness. Another advantage is that specimens can be viewed in color using light microscopy while it can only be viewed in black and white using electron microscopy.
Anton Leeuwenhoek was the father of microscopy.

Dark field microscopy (dark ground microscopy) describes microscopy methods, in both light and electron microscopy, which exclude the unscattered beam from the image. As a result, the field around the specimen (i.e. where there is no specimen to scatter the beam) is generally dark.

Depending on what microscopy you are doing.. Bacterial microscopy starts with 40x and Blood smear microscopy at 10x.

knowledge of microscopy helps to observe microorganisms and its behavior
The term "fluorescence microscopy" is a type of light microscopy in which the specimen is irradiated at wavelengths that excite fluorochromes. In medicine, it is used to detect antigens.

Electron microscopy gives higher resolution, but it's expensive, slow, and cumbersome. And for many things, it's not needed.

Phase-contrast microscopy is the observation of internal structures of living microbes where as bright field microscopy is the observation of killed stained specimens and naturally colored live ones.

Confocal Microscopy is used when the optical resolution needs to be increased. It also has a elimination of glares that are out of focus and a depth of field that is shallow. Compound Microscopy increases the details to the naked eye. It allows you to see things 1000 times there original size.
The person who is known as the Father of Microscopy is Zacharias Janssen. This is because he was the one who invented the microscope.
