EM stands for various terms. Discover the full forms, meanings, and possible interpretations of EM across different fields and industries.
An electron microscope is a microscope that uses accelerated electrons as a source of illumination. Because the wavelength of an electron can be up to 100,000 times shorter than that of visible light photons, the electron microscope has a higher resolving power than a light microscope and can reveal the structure of smaller objects.
EnvironmentMedicalA ridge of earth or rock placed, shaped and compacted to carry a road, railway, canal, etc., or to contain water.
