TeachMeFinance.com - explain Electromagnetic radiation Electromagnetic radiation The term 'Electromagnetic radiation' as it applies to the area of Earth observation can be defined as ' Energy propagated as time-varying electric and magnetic fields. These two fields are inextricably linked as a single entity since time-varying electric fields produce time-varying magnetic fields and vice versa. Light and radar are examples of electromagnetic radiation differing only in their wavelengths (or frequency). Electric and magnetic fields propagate through space at the speed of light'. The term 'Electromagnetic radiation' as it applies to the area of nuclear science can be defined as ' A traveling wave motion resulting from changing electric or magnetic fields. Familiar electromagnetic radiation range from x-rays (and gamma rays) of short wavelength, through the ultraviolet, visible, and infrared regions, to radar and radio waves of relatively long wavelength.
