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
