how can i tune a received ightwave like a guitar's strings and what is the energy required per kHz? Answered
Is a light wave like a guitar string?
Can i take a received electro magnetic wave and tune it? For instance, can I take white light into a device and change the waves properties so that it comes out as red light, or microwave radiation? The applications could be staggerring. If, for instance, I could take incoming sunlight and tune the wave so that the output was alternating current electricity. This would seem to me to be a far better way to harness the enormous energy contained in a lightwave.
