Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Used to scan the surface of an object, like an insect or something like that.
A
TEM
B
SEM
C
STM
D
ATM
Explanation: 

Detailed explanation-1: -This technique allows you to see the surface of just about any sample, from industrial metals to geological samples to biological specimens like spores, insects, and cells.

Detailed explanation-2: -Backscattered electron detector (BSD) In scanning electron microscopy (SEM), samples are imaged using a focused electron beam that is rastered across a surface. Different types of electrons are emitted from samples. A backscattered electron detector (BSD) detects elastically scattered electrons.

Detailed explanation-3: -As a result, TEM offers valuable information on the inner structure of the sample, such as crystal structure, morphology and stress state information, while SEM provides information on the sample’s surface and its composition.

Detailed explanation-4: -Scanning electron microscopy (SEM) analyses the surfaces of materials, particles and fibres so that fine details can be measured and assessed via image analysis.
