Answer 1

Electron microscopy (EM) is a technique for obtaining high resolution images of biological and non-biological specimens. It is used in biomedical research to investigate the detailed structure of tissues, cells, organelles and macromolecular complexes. The high resolution of EM images results from the use of electrons (which have very short wavelengths) as the source of illuminating radiation. Electron microscopy is used in conjunction with a variety of ancillary techniques (e.g. thin sectioning, immuno-labeling, negative staining) to answer specific questions. EM images provide key information on the structural basis of cell function and of cell disease.

Answer 2

An electron microscope projects a beam of electron on the specimen to obtain a detailed magnified image of the specimen.

It is a special type of microscope in which an electron is used in place of visible light.

With electron microscopes we can observe the small scale world that makes up most of the things around us.

An electron microscope is used for the study of molecular scale biological or non-biological specimens which are way smaller to observe by a normal microscope.
