I dont know much about that stuff... but isn't that spectum just used to explain like as compared with other forms of waves? I though that there was a big contravercy over weather light was a wave or a photon(or some other word I dont remember) xD

I think, I've heard of a car that runs on water... well not runs on exactly... it produces water.
The car combines H and O to make H2O. somehow that gives off electricity and powers the car.
