Scanning electron and transmission electron microscope
Give one benefit of a scanning electron microscope over the transmission electron microscope? Briefly explain it.
Expert
The SEM or scanning electron microscope has become more admired than the TEM or transmission electron microscope as it can generate images of high resolution, better clarity and three dimensional qualities and needs less sample preparation.

Newton: N (after Sir I. Newton, 1642-1727): The derived SI unit of force, stated as the force needed to give a mass of 1 kg of an acceleration of 1 m/s2; it therefore has units of kg m/s2.
The molecules of many dielectrics possess an electric dipole moment without having an external electric field. In such molecules centres of their positive and negative charges are displaced with respect to each other and therefore form a dipole. Such materials are kno

Ground source Heat Pumps (GSHP): This technology makes use of the energy stored in the earth’s crust, which comes mainly from solar radiation. Fundamentally, heat pumps take up heat at a certain temperature and discharge it at a higher temperatu

Rayleigh criterion: resolving power: The criterion for determining how delicately a set of optics might be able to differentiate. This starts with the supposition that central ring of one image must fall on the first dark ring of the other; for
Dielectric is a material in which energy can be accumulated. Ideally, it is a non-conductor of electric charge like insulators, but an efficient supporter of electrostatic fields. The
