gamma radiations..
UHF (Ultra High Frequency)
Right around the visible light band.
color
Immediately adjacent to the band of visible light, on the end with highest frequency / shortest wavelength.
Visible light.
That's the portion of the spectrum that we call "gamma rays".
The lowest frequency is effectively zero and this would be in the extremely low frequency (ELF) band in the sub-radio range of the electromagnetic spectrum.
That would be sound waves, or the audio spectrum.
Photons with higher energy correspond to electromagnetic radiation with higher frequency/shorter wavelength. In the visible band, the color with the highest frequency is the last one you can see on the VIOLET end of the spectrum.
UHF (Ultra High Frequency)
Gamma rays
The radio band is the least energetic section of the electromagnetic spectrum.
Right around the visible light band.
Immediately adjacent to the band of visible light, on the end with highest frequency / shortest wavelength.
color
The visible spectrum is one band within the full range of electromagnetic radiation.
That would be a spectrum or band.
