It's not easy to imagine how high the frequency of a high-energy gamma ray is. During the time it takes for its wave to go through one cycle, a gamma-ray wave traveling at the speed of light will ...

Each region of the electromagnetic (EM) spectrum has a range of wavelengths associated with it. Radio waves have the longest wavelengths and gamma rays have the shortest wavelengths. Radio waves ...

From the warm glow of the sun to audible radio waves and invisible gamma rays, electromagnetic waves (action between particles that have an electric charge) surround us. But did you know that there's ...

Fermi was launched on 11 June 2008; the satellite is named after the Italian nuclear physicist and Nobel laureate Enrico Fermi (1901-1954). Gamma radiation, the range in the electromagnetic spectrum ...

Among the most fascinating phenomena are gamma rays, the most energetic form of electromagnetic radiation. Recently, ...

There's lots to discover in the electromagnetic spectrum ... ultraviolet radiation, and X-rays. The tour ends with gamma rays, the potentially deadly radiation discussed in the program Death ...

Electromagnetic radiation is the general term for the more familiar light and radio waves, but also includes gamma rays, x rays, ultraviolet rays ... frequencies. The resulting spectrum (power vs.
