Radiation is energy that travels and spreads out as it goes-- visible light that comes from a lamp in your house and radio waves that come from a radio station are two types of electromagnetic radiation. Other examples of EM radiation are microwaves, infrared and ultraviolet light, X-rays and gamma-rays.

The spectrum usually is divided into seven types of radiation: radio, microwave, infrared, visible, ultraviolet, x-ray, and gamma-ray radiation. Different types have different frequencies of waves. Whether the frequency is high or low, all electromagnetic waves travel at 300,000,000 meters per second.

The electromanetic spectrum is well explained in any good physics text book. Gamma rays are just one particular frequency per f = c/2piR where R is the radius of the Atom at about 10 to the exponent power of minus 8. Turns out to be an aver...

The modern value for this speed is 300,000 km/s, or 300 million m/s (also written as 3 x 108 m/s). In miles it works out to 186,000 miles per second (seven times around the earth in one second). ... Just before the turn of the century, four types of electromagnetic radiation were known: Radio Waves, Infra Red,
