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

1. What is the core principle?Assigning visible colors to data representing non-visible phenomena or spectral bands
2. What is the primary data sources?Multispectral and hyperspectral imaging sensors, medical imaging devices (MRI, CT)
3. What is a false color image?False color images use bright colors to show light that we normally can’t see, like infrared, so we can understand hidden details.
4. Why do scientists use false color instead of true color?They use it to highlight special features, like plant health or hidden minerals, that would be invisible in normal pictures.

Electromagnetic Spectrum: The full range of electromagnetic radiation, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
Multispectral Imaging: Capturing image data at several discrete spectral bands, often including non-visible ones.
Remote Sensing: The science of obtaining information about objects or areas from a distance, typically from aircraft or satellites.
