Check out this low cost project. This video will show you how to transfer sound over light! Yes, this is possible. You'll transfer a sound with a distance of 5 meters, but you may experiment on greater distances if you'd like. You'll need a laser (or an LED) for this audio project, one Opto transistor (or resistor), one 3-volt battery, two mono audio jacks, and some alligator clips. Just watch this cool electronic audio experiment and try it out yourself.

awesomest thing to do on halloween. slipknot and alot of freetime equals a bunch of scared kids ^.^
Isn't that transfer of pulsed signal, and the sound is from speaker which is activated by the laser or LED, not light making sound? Light provides electro-magnetic with photons, since it is battery driven?
thank u
I am making this for my science project....but i dont know the principle behind it.....can you plz tell me the principle behind this, like why does this actually work....how does sound get converted to light and all.....plz its urgent
