WebThe IR spectrum is situated between the visible and microwave regions of the electromagnetic spectrum. In terms of wavelength, it spans from 0.75 micron, which is abbreviated μ, to 12 micron and can be classified into 4 sub-bands: Near Infrared (NIR), Short Wave Infrared (SWIR), Mid Wave Infrared (MWIR), and Long Wave Infrared (LWIR.) WebOf its 11 bands, only those in the very shortest wavelengths (bands 1–4 and 8) sense visible light – all the others are in parts of the spectrum that we can’t see. The true-color view …

6.3: IR Spectrum and Characteristic Absorption Bands

Radio waves are emitted and received by antennas, which consist of conductors such as metal rod resonators. In artificial generation of radio waves, an electronic device called a transmitter generates an AC electric current which is applied to an antenna. The oscillating electrons in the antenna generate oscillating electric and magnetic fields that radiate away from the antenna as ra… WebThe Spectral Characteristics Viewer is an interactive tool that can be used to visualize how the bands, or channels, of different satellite sensors measure the intensity of the many wavelengths (colors) of light.
