NASA - The Electromagnetic Spectrum - X-Rays
X-rays have much higher energy and much shorter wavelengths than ultraviolet light, and scientists usually refer to x-rays in terms of their energy rather than their wavelength. This is partially because x-rays have very small wavelengths, between 0.03 and 3 nanometers, so small that some x-rays are no bigger than a … See more X-rays were first observed and documented in 1895 by German scientist Wilhelm Conrad Roentgen. He discovered that firing streams of x-rays through arms and hands created … See more The physical temperature of an object determines the wavelength of the radiation it emits. The hotter the object, the shorter the wavelength of peak emission. X-rays come from objects … See more Solar storms on the Sun eject clouds of energetic particles toward Earth. These high-energy particles can be swept up by Earth's magnetosphere, creating geomagnetic storms that sometimes result in an aurora. The … See more Since Earth's atmosphere blocks x-ray radiation, telescopes with x-ray detectors must be positioned above Earth's absorbing atmosphere.

WebMay 31, 2024 · X-rays work by being absorbed in denser material, producing the shadow that is the traditional X-ray image. Medical X-rays are designed to top out looking at calcium-40 ( Z =20). On an object the size of the Earth, the X-ray shadow isn't going to differ much from the optical shadow (except of course, for the atmosphere). greensand commons
