I wonder how thoughtful the nature is... that it made only part of the entire Electro-magnetic wavelengths as 'Visible' spectrum. Meaning - in the whole range of radiation, only a fraction of them - those rays that comes out of light - (VIBGYOR) is visible to human eye.
Just imagine how horrible it would be if the visible spectrum had included the Radio frequency into it.. You will start seeing every single ray that is transmitted from a radio station, cell phone tower, remote control etc. There would be millions of such rays running all over the place. Lets consider the cell phone signals alone - how many people in your area would be talking at a given moment? Each of them would be receiving a signal from the cell phone tower near by, all the way to their phone - so how many rays will there be roaming in a crowded city? Assume each of those are thick ray of green colored light, like the laser lights in a Discotheque club - how will that be? Luckily we stay blinded to them as if they are colorless.
And remarkably - nature did think about this millions of years before man could discover their use!!
