Summary[edit]

Description
English: Graphs of reflectance vs. wavelength of snow, water, vegetation, and dry soil. A reflectance spectrum shows the wavelengths (colors) of light that reflect off a surface. Different materials on Earth’s surface have different spectra because they reflect sunlight in different ways. (Human eyes can distinguish between snow, water, vegetation, and soil based on their color, which is a result of the various wavelengths they reflect.) Earth scientists use reflectance spectroscopy to study rocks, soil, ocean water, ice caps, mineral deposits, forests, farmland, dust storms, volcanic eruptions, and even wildlife. Planetary scientists can compare the reflectance spectrum of a distant planet to reflectance spectra of different materials on Earth’s surface to figure out what rocks, minerals, liquids, and ices could be on the planet.

Metadata

This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.
