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. What is the modern x-ray sources?Synchrotron radiation facilities offer high intensity, tunability, and coherence for advanced studies
2. How does X-ray diffraction show the inside of crystals?When X-rays hit a crystal, the atoms act like tiny mirrors and send the rays out at special angles, making a pattern that shows how the atoms are arranged.
3. Who discovered that X-rays can diffract and why is it important?Max von Laue first showed that crystals can bend X-rays, and later the Bragg brothers created a formula that lets us calculate the crystal’s structure.

Elastic Scattering: Scattering where the incident particle (X-ray) retains its energy.
Lattice Parameters: The dimensions and angles defining the unit cell of a crystal structure.
Fourier Transform: A mathematical process used to convert a signal from one domain to another, here electron density to diffraction pattern.
