A radiograph (X-ray) is a photographic image generated when the electromagnetic radiation interacts with the X-ray film after passing through an object. The density of a material will affect how much radiation gets to the film. Most dense: metal (radiopaque), bone, tissue, liquid, air (radiolucent). Radiopaque = impermeable to x-rays; gives a ...

X-rays are a short-wavelength, high-frequency form of EM radiation with wavelengths in the range of 10^-8 to 10^-13m. How are x-rays similar and different to gamma rays? X-rays are the same as γ-rays, except in the way they are produced.
Aug 10, 2016 · TEMPERATURE AND COMPOSITION. 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 that are millions of degrees Celsius—such as pulsars, galactic supernovae remnants, and the accretion disk of black holes.
Nov 17, 2014 · By looking at the sky with X-ray and gamma-ray instruments, we collect important information in our attempt to address questions such as how the universe began and how it evolves, and gain some insight into its eventual fate.
X-ray astronomy, Study of astronomical objects and phenomena that emit radiation at X-ray wavelengths. Because Earth’s atmosphere absorbs most X-rays, X-ray telescopes and detectors are taken to high altitudes or into space by balloons and spacecraft. In 1949 detectors aboard sounding rockets.
