Are we able to share the files using light waves?

Place a screen at some distance in front of the the light source. Make sure it is opaque. Punch two pin holes on the screen some distance apart from each other. Now these two holes act as two separate sources of light which are coherent. It is so because they are derived from the same main original source. read more

Or if you want to obtain more and more coherent light, you may bombard surface of a photoluminesce Photoluminescence matter by the photons of your light. The radiated light will be pure after emission. read more

And those that we can see with our eyes are just a small fraction of the big spectrum of light waves. The light waves that that help us understand the world around us and to see colours and stuff like that are called Visible Light Waves, and they are kind of in the middle of the spectrum. read more
