Frequency and Wavelength of Energy in the Electromagnetic SpectrumEnergyFrequency in hertzWavelength in meters
gamma-rays 1020-1024 <10-12 m
x-rays 1017-10201 nm-1 pm
ultraviolet 1015-1017400 nm-1 nm
visible 4-7.5x1014750 nm-400 nm
near-infrared 1x1014-4x10142.5 um-750 nm
infrared 1013-101425 um-2.5 um
microwaves 3x1011-10131 mm-25 um
radio waves <3x10 11>1 mm
Sorry for the crappy chart it is on the of this link http://www.spacetoday.org/DeepSpace...vatories/Chandra/ElectromagneticSpectrum.html
gamma , xray , and ultraviolet waves do they make recievers /transmitters using these frequencies other then for use in theortical or astronomical observations??? Other then xrays being used in medical xray machines for imaging the human body. What other things are these frequencies used for seems to me anything over visible light would be harmful to a human and is not really practically to use. <-- maybe these high frequency spectrums are only used in astronomy for detecting the universe ,....etc etc Could be wrong though ?
Also I have no idea if ultravoilet waves are ever in use for something other then maybe a tanning place or medical something?
Does the FCC have any regulations for these frequency bands or do the FCC just have regulations set for radio , microwave , infrared , and visible light?
Curious to know how much allocation for the microwave , infrared , visble light ,....and higher spectrums. I know RF waves are pretty much all allocated and restricted to certain things by the FCC?
I know microwaves are used for radar , and weatherforcasting , ...etc
What I am looking for is a chart that lists all the frequencies what they are using them for , what modulation techquie , and how much bandwidth is allocated to them.
I want to know this to better understand how the whole spectrum is being used.
And most importantly where the unallocated regions of the spectrum are.
Thanks
