Laser ~VS~ Fiber Optics

For the scientific aspects of light, you should read up on Wikipedia or something.

However, with the laser communications, just because they shined some powerful laser off a mirror on the moon and detected a few photons doesn't make it a good communications method. Back before scientists developed high-quality glass fabrication techniques for fiber-optics they tried using line-of-sight laser communications. Unfortunately, they were very prone to interference and it was just as easy, or easier to use microwaves or wire-based communications. Fiber-optics are used because they are extremely low loss over long distances, so you don't need to degrade the signal with amplifiers as much, or worry about interference. It's also cheap to use (the fibers that is).

Was I correct with my 'mini-explanation', it doesn't cover everything, but it helps answer his/her questions.

That depends If by correct you mean were your explanations of the different theory's accurate, in which case from what I read it seemed pretty good. But is the actual theory correct? No one knows yet, in 10 years time we could learn that light is a conscious living form of energy... Who knows.

Well, yeah, I wasn't explaining that I know all about light, I was explaining what we believe we know, the theories etc.

Radio waves are a form of electromagnetic radiation too, just like light.
