EM radiation is the energy propagated through free space or through a material medium in the form of electromagnetic waves.
Examples include radio waves, infrared radiation, visible light, ultraviolet radiation, X rays, and gamma rays. Electromagnetic radiation exhibits wavelike properties such as reflection, refraction, diffraction, and interference, but also exhibits particlelike properties in that its energy occurs in discrete packets, or quanta. Though all types of electromagnetic radiation travel at the same speed, they vary in frequency and wavelength, and interact with matter differently. A vacuum is the only perfectly transparent medium; all others absorb some frequencies of electromagnetic radiation.
EM is short for electromagnetic.
In a vacuum, 3x10^8 ms^-1. Basically the speed of light, it is EM radiation afterall.
infrared radiation ;)<3
Gamma radiation
In 10.7 femtoseconds, em radiation will travel 3.208 E -6 meters. EM radiation travels at the speed of light, or 299, 792, 458 m/s.

The electromagnetic (EM) spectrum is a name for different types of radiation. Most radiation comes from the sun. Want more info?

Heat radiation is mainly associated with infrared radiation.
Visible light is a very small part of the EM spectrum and it is intellectual laziness to refer to all EM radiation as light.
Saturn does not have an ozone layer. It is for that reason it cannot absorb EM waves.
