 Author Rajakani Electromagnetic spectrum continuation.... Previous post about EMspectrum Visible Spectrum We are all see and enjoy colors from our day to day life. Human eye has some limitation to sense particular wavelength of electromagnetic spectrum, those are all we call as "visible light".  sun is the main natural source light up the world. Here, dispersion of light get VIBGYOR colors which means shorter wavelength to longer wavelength 3000-7000 Armstrong. oh ok how other colors are form like brown, black, pink etc. I n White light formation was depend on Primary colors like RGB model. RGB model is nothing Red, Green, Blue . combination of these 3 colors to form a white light.  its fully depends on light intensity if you have high intensity light of these 3 colors to form white light. sadly, if you do it in home with these 3 color crayons you get dark color only. because, proper mixture of these 3 colors only you get white. these RGB model was worked in most of day to d

Authors Rajakani,  Bartholomew Richard Electromagnetic Spectrum Electromagnetic Spectrum is a combination of different electromagnetic waves with different frequency. EM waves were order from lower frequency to higher frequency range. oh what are that? " Radio waves, Microwaves, Infrared, Visible, UV, X Ray, Gamma Ray" How to remember everything., it is easy dude.

Clark Maxwell first predicted radio waves with his theory, which measured as unit in Hz. you turn on a radio, the radio receives the radio waves in the air and converts them into an electrical signal, which is converted to sound waves, and the radio amplifier then boosts the sound waves so that you can hear the music. Figure Credit : India times      radio wave is broadcast in different frequencies which can include FM radio waves that broadcast between 88 MHz and 108 MHz, and AM
