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 detection technology?Thermographic cameras detect infrared thermal radiation to create temperature-sensitive images
2. Why do we see a red glow when something gets hot?When an object gets very hot, its thermal radiation moves into the visible light range, making it glow red, orange, or yellow.
3. How do we use thermal radiation to see in the dark?Thermographic cameras capture infrared light that warm objects emit and turn it into pictures that show where heat is.

Electromagnetic Spectrum: The range of all types of electromagnetic radiation, including radio waves, visible light, and X-rays.
Infrared Radiation: Electromagnetic radiation with wavelengths longer than visible light, commonly associated with heat transfer.
Blackbody Radiation: The theoretical spectrum of electromagnetic radiation emitted by an idealized object that absorbs all incident radiation.
Thermography: The use of infrared imaging cameras to detect and visualize temperature variations.
