## 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 vaccum 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
