Final answer:
The IR spectrum consists of Near-infrared, Mid-infrared, and Far-infrared regions, ranging from the visible spectrum edge to much longer wavelengths. Infrared is often associated with heat radiation emitted by objects at temperatures experienced in everyday life. The IR spectrum can be broken down into three regions which are correctly identified as B) Near-infrared, Mid-infrared, and Far-infrared.
Step-by-step explanation:
The IR spectrum can be broken down into three regions which are correctly identified as B) Near-infrared, Mid-infrared, and Far-infrared. These regions correspond to different wavelength ranges and are associated with varying energy levels within the infrared part of the electromagnetic spectrum.
The near-infrared region is the closest to the visible spectrum and ranges from approximately 700 nm to 2500 nm (0.7 to 2.5 micrometers), the mid-infrared from about 2500 nm to 25000 nm (2.5 micrometers to 25 micrometers), and the far-infrared extends from 25000 nm to 1000000 nm (25 to 1000 micrometers). Infrared radiation is often referred to as "heat radiation" as it's given off by objects at temperatures common in our daily environments.
