In the study of X-rays and gamma-rays up to the TeV regime, their absorption by the atmosphere (by 50% at 30 km altitude for 1 MeV photon) requires the development of space applications. The science goals of the mission define which technological benchmark should be maximised (e.g. ...
X-rays: X-rays are very high-energy light waves. We're most familiar with their use in a doctor's office, but X-rays also naturally occur in space. But don't worry, X-rays can't penetrate from outer space to the Earth's surface. Read more in How X-rays Work. Gamma rays: Gamm...
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 photons (see How Light Works for details). The difference between X-rays and visible light rays is the energy level of the individual ...
Explain why int_{0}^{1} square root{1 + x} d x is more than or equal to int_{0}^{1} square root{1 + x^2} d x. What is the difference between rilles and rays? How was Pascal's triangle discovered? Can a different three-dimensional object appear in the same orthographic drawi...
What form of electromagnetic radiation do X-rays use? How much electromagnetic radiation is harmful? How is information transmitted through electromagnetic radiation? Which type of electromagnetic radiation has the highest frequency? In what ways are sound waves and electromagnetic waves different?
There are two types of electromagnetic radiation you should concern yourself about; gamma and x-rays. First let’s start with gamma rays. In certain radionuclides the atom’s nucleus is left in an excited state after beta or alpha decay. This energy is then released via a very high energy...
X-rays, another form of electromagnetic energy, are also a form of ionizing radiation. Check out How Nuclear Radiation Works for more information. Relatively speaking, alpha and beta particles cannot penetrate very far into matter. Gamma rays and X-rays, on the other hand, can penetrate matter...
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...
Some examples of high energy photons emitted by the sun include gamma rays, X-rays, and ultraviolet radiation (UV rays). Whereas the heat that we feel from the sun comes from lower energy photons which make up infrared radiation. The majority of solar energy that makes it to Earth lies ...
Nuclear materials — substances that emit nuclear radiation — are fairly common and have found their way into our normal vocabularies in many different ways. You have probably heard (and used) many of the following terms: Uranium Plutonium Alpha rays Beta rays Gamma rays X-rays Cosmic ray...
