The electromagnetic radiation spectrum chart.This chart includes all known ranges of EMR (ElectroMagnetic Radiation) The emanation of energy from everything in the universe. Although the EMR from electrical and electronic devices is typically measured for practical, every-day situations, every object, including humans, emanates energy. including: gamma rays, X-rays, ultraviolet light, visible light, infrared, microwaves, radio waves (ULF ULF abbr. ultralow frequency , VLF (Very Low Frequency) See low radiation. , LF, MF, HF, long, short, HAM, VHF, UHF, SHF, EHF), cosmic microwave background radiation Noun 1. cosmic microwave background radiation - (cosmology) the cooled remnant of the hot big bang that fills the entire universe and can be observed today with an average temperature of about 2. and brain waves, all organized by octaves. The audio frequency spectrum is also included. Descriptions are included for all ranges and properties of EMR, including reflection, refraction, LASER, television, gravity waves, emission and absorption. There is also a chart of SI unit prefixes ranging from yocot to yotta. All items are placed on the graph using custom programmed formulas. Great chart on a difficult subject!
