X-rays are essentially the same as gamma rays, but their origin is different. Where gamma rays come from inside the nucleus of an atom, X-rays come from processes outside the nucleus. X-rays come from a change in the electron structure of an atom and are mostly machine-produced. They ...
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 ...

AimsThe effects of irradiation (gamma-rays and electron-beams), up to 10 kGy, in the antimicrobial activity of mushroom species (Boletus edulis, Hydnum repandum, Macrolepiota procera and Russula delica) differently processed (fresh, dried, freeze) were evaluated.Alves, M. J.Fernandes, A.Bar...
The atmospheric Cherenkov gamma-ray telescope MAGIC, designed for a low-energy threshold, has detected very-high-energy gamma rays from a giant flare of the distant Quasi-Stellar Radio Source (in short: radio quasar) 3C 279, at a distance of more than 5 billion light-years (a redshift of...
Gamma rays and cosmic rays are high-energy particles and radiation that originate from various sources in the universe, such as supernovae, black holes and even the Big Bang itself. Scientiststheorizethat antimatter should be as abundant as ordinary matter because of the Big Bang, but it's sc...
or CCD. Some space telescopes use a complementary metal-oxide-semiconductor (CMOS) active-pixel sensor, such as theWISPR imageron the Parker Solar Probe. These sensitive instruments can detect photons from the infrared to gamma rays because of how photons interact with the electrons in the sensors...
1、观察宇宙首先用到的是光,可见光First there was light,visible light.然后我们用无线电和X射线观察宇宙Then, we viewed the universein radio waves and X-rays.自从天文学诞生以来Ever sincethere's been astronomy,我们一直在观测不同种类的光we've been looking atdifferent kinds of light并利用更长的曝光...
As it turns out, the basic process is really very simple. Contents What's an X-Ray? The X-Ray Machine Are X-Rays Bad for You? What's an X-Ray? X-rays are basically the same thing as visible light rays. Both are wavelike forms of electromagnetic energy carried by particles called ...
