Which band corresponds to the range of wavelengths between 0.4 and 0.5 micrometers?

The blue band corresponds to the range of wavelengths between 0.4 and 0.5 micrometers. This range captures the shorter wavelengths of visible light, which is perceived by the human eye as blue. In remote sensing and various applications in GIS, different bands are utilized to capture specific characteristics of the Earth's surface. The blue band is particularly significant for understanding water bodies, vegetation health, and atmospheric conditions because it interacts differently with different materials.

In the context of the other options, the green band typically covers a range from about 0.5 to 0.6 micrometers, the red band ranges from approximately 0.6 to 0.7 micrometers, and the yellow band, while less commonly defined in standard remote sensing, generally falls between the green and red bands. These distinctions clarify why the blue band is the correct choice for this specific wavelength range.
