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 data acquisition principle?Collects and processes spectral information for each pixel, creating a spectral profile
2. What is the primary scientific applications?Astronomy, agriculture, molecular biology, biomedical imaging, geosciences, physics, and surveillance
3. How does hyperspectral imaging help scientists?By looking at the unique spectral signatures of each pixel, scientists can identify what materials are present, measure how much of something there is, and learn about physical properties without touching the object.
4. Why is hyperspectral imaging useful for farmers?It can spot crop stress, missing nutrients, or disease early, so farmers can treat plants before problems become big and use water and fertilizer more wisely.

Electromagnetic Spectrum: The full range of electromagnetic radiation, including visible light, infrared, and ultraviolet.
Spectral Signature: A characteristic pattern of light absorption and reflection exhibited by a substance across different wavelengths.
Data Cube: A three-dimensional array of data representing spatial dimensions (x, y) and spectral dimension (wavelength).
