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

1. How long is X-ray?Approximately 0.01 to 10 nanometers
2. Who discovered X-ray?Würzburg, Germany
3. What is the discoverer?Wilhelm Conrad Röntgen
4. What is the primary interaction mechanisms?Photoelectric effect and Compton scattering
5. What are X-rays and how do they let us see inside things?X-rays are a special kind of light that can go through many materials. They make a picture by showing how much each part stops the light.
6. How did scientists first discover X-rays?In 1895 a scientist named Wilhelm Röntgen noticed a strange glow from a tube and found that it could pass through things and make pictures on film.

Ionizing radiation: Radiation with enough energy to remove electrons from atoms and molecules, potentially causing damage.
Photoelectric effect: The emission of electrons or other free electrons when light shines on a material.
Compton scattering: The inelastic scattering of a photon by a charged particle, usually an electron.
