Electromagnetic Radiation
Electromagnetic Radiation  is observed in Dipoles consists of two straight wire of different polarities carrying current. Electromagnetic Radiation is spread out as an ElectroMagnetic Wave that compose of an ElectroMagnet Wave perpendicular to an Electric Wave

Characteristics of Electromagnetic Radiation
''Electromagnetic Radiation travels at a speed equal to speed of light in a vacuum C = 3 x 1018 and has a Quanta Energy Level. ''
 * v = C = λ f


 * $$\lambda = \frac{C}{f}$$
 * $$ f = \frac{C}{\lambda}$$


 * E = h f = h nfo = $$h \frac{C}{\lambda}$$

Electromagnetic Radiation Spectrum
Electromagnetic Radiation Spectrum used in communication include frequencies of
 * ../Radio Waves/, wave of frequency in the range of 2KHz - 20 KHz
 * ../Microwave/, wave of frequency > 3MHz
 * ../Visible Light/, wave of frequency > 3 THz
 * ../Ultra Violet Waves/, wave of frequency > 3GHz
 * ../X Rays/ ,
 * ../Gamma Rays/ ,



Wavelength and Frequency of Electromagnetic Radiation

 * Visible Light has a frequency spectrum
