Ultraviolet light is a part of the electromagnetic spectrum. Ultraviolet rays have frequencies greater than the frequency of visible light but lower than the frequency of X-rays. The wavelength of ultraviolet light is shorter than visible light and longer than that of X-rays. On interaction wit...
How do gamma rays interact with matter? Why are gamma rays dangerous? Are gamma rays light? What is the wavelength of gamma rays? What is alpha radiation? What causes gamma ray bursts? What are cosmic rays used for? What is beta ionizing radiation and their properties?
The latter unit is used to measure shorter wavelengths on the electromagnetic spectrum, such as UV radiation, X-rays and gamma rays. Conversely, radio waves have much longer wavelengths, reaching anywhere from 1 mm to 100 km, depending on the frequency. ...
Gamma-ray astronomy has become a rich field of research and matured significantly since the launch of NASA's Compton Gamma Ray Observatory in April 1991. Studies of the diffuse gamma-ray emission of the Galaxy can now be performed in far more detail and extended into the MeV regime, ...

Gamma Brainwaves Gamma rays are the fastest of brain waves (high pitch, like a flute), and relate to simultaneous processing of information from different brain areas. It passes information rapidly, and as its most subtle of the frequencies, the mind has to be quiet to access it. It is hi...
Powerful magnetic fields channel electrically charged material to the poles of the new black hole, where it is blasted out as two polar jets moving at near light speed. These jets emit X-rays and gamma-rays as they barrel through surrounding stellar matter, and these initial high-energy ...
More interesting still, the conjectured mass range for the DM candidate ($65$ - $100$ GeV) lies within the region of models viable to try explain the recent Galactic Centre (GC) gamma-ray excess seen by Fermi Large Area Telescope (Fermi-LAT) and the High Energy Stereoscopic System (HESS...
So, gamma rays have the most energy (part of what makes them so dangerous to humans), and radio waves have the least. Of visible light, violet has the most energy and red the least. The whole range of frequencies and energies, shown in the accompanying figure, is known as the ...
while x-rays originate in theelectron cloudaround the nucleus. Astrophysicists distinguish between gamma rays and x-rays strictly by energy. Gamma radiation has a photon energy above 100 keV, while x-rays only have energy up to 100 keV. ...
