Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
TEM operates by passing a high-voltage electron beam through an ultra-thin specimen.
Step 2: Meaning
As electrons pass through the sample, they interact with the atoms in the specimen.
Step 3: Analysis
The primary mechanism for image contrast in TEM is the scattering of electrons (both elastic and inelastic) as they encounter different densities within the material. Denser areas scatter more electrons and appear darker.
Step 4: Conclusion
Therefore, scattering is the fundamental interaction used to form the image. Final Answer: (D)
