Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How big is Convergent beam electron diffraction?High-resolution characterization of crystalline materials at the nanoscale
2. What is Convergent beam electron diffraction known for?Enables determination of crystal symmetry, lattice parameters, and strain
3. What is the methodology?Utilizes a convergent or divergent electron beam for material analysis
4. What is the key analytical output?Generates diffraction discs containing detailed crystallographic information
5. Why do scientists use a convergent beam instead of a parallel beam?A convergent beam makes small, detailed patterns that show information about tiny parts of a crystal, which a parallel beam cannot provide.
6. How does CBED help make better airplanes?It lets scientists see the exact crystal phases and orientations in alloys, so they can design stronger, heat‑resistant materials for aircraft.

Bragg Diffraction: The scattering of X-rays or electrons by the atomic planes in a crystal at specific angles.
Lattice Parameters: The precise distances between atoms and the angles between them in a crystal's repeating unit.
Space Group: A classification system that describes the full symmetry of a crystal structure.
