Explain how x-rays are produced when an electron beam falls on a metal target. Is there a metal-metal bond in (Cu(OAc)_2(H_2O))_2? Explain. Explain what incomplete combustion is and what the significance is to the health of someone who is exposed ...

Even though dark matter is invisible, astrophysicists know it exists. Without this dark matter, it is impossible to explain how the visible things in the universe hang together. The image shows all the gamma rays recorded by the Fermi-LAT space probe as a map of the entire universe. The r...
How are gamma, beta and alpha radiation all alike? Describe the general effects of alpha, beta, and gamma radiation on living cells. How is beta radiation formed? How are gamma rays produced? What gives off gamma rays? Why is gamma radiation ionizing radiation? How are ...
Ernest Rutherford was the first to discover alpha, beta, and gamma rays. Noble gases, electrons, protons, lanthanides and actinides were also discovered by several other scientists. The periodic table began with just forty-seven elements, and now we have over one-hundred. We are at one-...
To characterize the oscillation properties of the disk and predict the strength of gravity, X-ray observations are essential. Obtaining QPO frequencies from X-rays is a significant step in understanding the characteristics of both the black hole and the disk. However, understanding the physical ...
In a core-collapse supernova, ALPs would be emitted via the Primakoff process, and eventually convert into gamma rays in the magnetic field of the Milky Way. The lack of a gamma-ray signal in the GRS instrument of the SMM satellite in coincidence with the observation of the neutrinos ...

γ-rays are also the highest energy photons, so a space opera might have ships flying near the speed of light firing gamma-ray weapons that go PEW PEW. γ is also used as the symbol for the Euler-Mascheroni constant and occasionally as a variable or function name. ...
I added a link to the radiative zone (where gamma rays spend 171 thousand years colliding with matter, getting longer wavelength at each collision, until they leave) but somebody should probably learn about all the different zones at some point and make sure the text is correct. I never ...
