Physics Course/Electromagnetic Radiation

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

• [[../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
