WebAug 2, 2024 · The main bands used, in order of decreasing wavelength (hence increasing frequency and photon energy) are: Radio. Microwaves. Infra-Red. Visible light. Ultra … WebThe S band is a designation by the Institute of Electrical and Electronics Engineers (IEEE) for a part of the microwave band of the electromagnetic spectrum covering frequencies from 2 to 4 gigahertz (GHz). Thus it crosses the conventional boundary between the UHF and SHF bands at 3.0 GHz.
