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.

Tesla: T (after N. Tesla, 1870-1943): The derived SI unit of the magnetic flux density stated as the magnetic flux density of a magnetic flux of 1 Wb via an area of 1 m2; it therefore has units of Wb/m2.
