I understand that there is such a thing as the electro magnetic spectrum, and that light and RF are both on it, so dose that mean that they are made of the same thing? Just at different frequencies.
you see, the point here is waves are just oscillating energy vectors.
Do you consider a male voice and a female voice as same? Then yes, visible light and RF waves are same!
Its only a matter of how much energy each of them is carrying.
While, RF is having lower photon energy than visible light attributed because of the frequencies.
