How fast do seismic surface waves travel? What is the speed of light in air? What gives off gamma rays? What is the equation for the speed of light? An x-ray is taken using x-rays that have a wavelength of 528 \times 10^{-12} m. What is the frequency in vacuum of these x-ra...
Gamma-ray astronomy has become a rich field of research and matured significantly since the launch of NASA's Compton Gamma Ray Observatory in April 1991. Studies of the diffuse gamma-ray emission of the Galaxy can now be performed in far more detail and extended into the MeV regime, ...
