Question 1: How We Learn About Objects of Interest to Intelligence through MatterEnergy Interaction: Refraction, Reflection, Emission, and Absorption
Energy and matter interactions in the atmosphere determine spectral regions important
in remote sensing. As such, intelligence and knowledge on energy interactions foster
interpretation of remotely sensed images, based on properties such as emission, absorption,
reflection, and refraction ("Resolutions of Remote Sensing," 2020). Principally, we learn
about objects of interest to intelligence through the electromagnetic spectrum, which helps
observe the properties of stars and planets, radial velocity, and surfaces' temperature,
including the object's chemical composition. For instance, atmospheric absorption results in
energy loss to atmospheric constituents. This scenario usually involves energy absorption at
specified wavelengths, which strongly influences intelligence and checks spectrally in remote
sensing systems. Different features also have varying reflection properties at various
wavelengths, revealing spectral information like the color of a reflecting surface and other
reflectance characteristics, thereby contributing to objects' intelligence through the matterenergy interaction ("Remote Sensing, Satellite Imaging Technology | Satellite Imaging
Corp," 2020).
The interrelationships between mechanisms of transmission, reflection, absorption,
and refraction also foster learning about specific objects of interest. Electronic intelligence
(ELINT) collectors and scientists use these properties to ascertain the composition of
absorbent materials, the chemical makeup of reflecting objects, and the wavelength and
direction of energy emanated. Intelligence on various objects can be acquired by these
professionals, especially ELINT collectors who use matter and energy interactions guided by
the electromagnetic spectrum to identify military weapons and intercept communication
