Question

For which of the following
information we can use SEM at very
lesser extent?
a)
Morphology
b)
Composition
c)
Topology
d)
Surface appearance​

Answer 1

Answer:

Option C

Explanation:

Among the various options given in question statement, the correct answer is Topology. Topology is related to the structure of a network or a chain and SEM does not find its application in topology.

SEM stands for Scanning electron microscope. SEM finds its application in determine the microstructure and morphology of the materials. In this technique, an electron beam with low energy is subjected on the surface under observation. As the beam enters, it gives out different photons and electrons  

Answer 2

c)  Topology we can use SEM at very  lesser extent.

Explanation:

• The topology deals with the geometric shapes that undergo continuous deformation. The deformation includes crumpling, twisting, and stretching.
• The shapes undergo continuity during deformation. Some of the deformations are homeomorphisms and homotopies.
• Topology is applied in programming language semantics; cut, twist, and reconnect the DNA; condensed matter physics; and configuration space.
• Scanning electron microscope (SEM) give images by scanning the surface through electron beam.
• The morphology, composition and surface appearance​ are majorly given by SEM but topology is given by mathematics and use of SEM in topology is very less.
