The wavelength range of Infrared radiation is 700 nanometers to 1 millimeter.
The sun emits mainly near-infrared which is mainly composed of wavelength below 4 micrometers.
The thermal range of infrared ranges between wavelengths 3.5 and 2.0 micrometers
Explanation:
The wavelength range of Infrared radiation is 700 nanometers to 1 millimeter. This also translates to a frequency range of 430 TeraHertz to 300 Giga Hertz.
Because the sun is a star and is hot in comparison to earth and other planetary bodies, the bigger range of infrared radiation it emits is in the near-infrared which is mainly composed of wavelength below 4 micrometers.
The earth's surface produces infrared radiation of the mid-infrared range while cooler substances will produce far-infrared range
The thermal range of infrared ranges between wavelengths 3.5 and 2.0 micrometers and is produced by black bodies.
The kinetic energy theory of matter states that all particles of matter are in constant motion. Kinetics has to do with some kind of movement, which is why this answer is the only plausible one.
