INTRODUCTION TO THE ELECTROMAGNETIC SPECTRUM.

The electromagnetic spectrum is the range of electricity that characterizes electromagnetic radiation. It propagates through area as combined waves of electrical and magnetic energy. Whenever a magnetic subject is generated, a corresponding electric field is also generated. The two fields journey as a wave and are perpendicular to each other. Radiation is any shape of energy that travels through space. Electromagnetic radiation travels simultaneously as waves of various frequencies, and as particles referred to as photons. Radio waves have a low frequency at approximately 10,000 Hz (hertz — waves per second) and have a completely big wavelength of approximately 1000meters, whilst gamma rays have a totally high frequency (1020 Hz) and a totally quick wavelength (10-12 m).  Visible light is a form of electromagnetic radiation with intermediate frequency and wavelength.  The extra the frequency of the electromagnetic radiation, the more the amount of energy related to each photon.
