Yer.. I'm lazy and tired, did not enough research and found out that the radio/electromagnetic wave makes all the electrons move back and forth when the wave oscillates between the magnetic and electric fields.... so you can see how much the current oscillates etc. But... um cameras work differently, the wave collapses so you get one signal of a wave and colour, much simpler.... what about quantum mechanics, don't the large wavelengths collapse as much? Well in general I dont know well enough how long wavelength EM-waves are detected, I've seen those pics from deep space where they detected intergalatic radiation. Anybody care to explain? or give links, names of phenemonas etc? I'm curios I NEED to know this.
