how to change sound wave to electric energy and yield light energy?

Question

give me the simple experiment.

Answer 1

well...

how about any type of flexible diaphragm connected to a small Faraday generator ( the magnet moving through a coil) that in turn is connected to a light bulb?

It would have to be a rather large diaphragm, with possibly a cone to catch and concentrate the sound wave to provide the mechanical movement in and out of the Faraday coil, but id bet it could be done.

Answer 2

Hi. Every microphone changes sound energy to electrical energy. An efficient LED may be powered by this energy.

Answer 3

actually, no. No you won't be able to. Sound waves themselves are ability, particular, even although that's merely the momentum/inertia of particales vibrating via a medium (air/water/partitions/et cetera). while somebody says "hi" to you, that's merely their vocal cords vibrating the air debris, your ear drums finding out on up that vibration, and your strategies translating the vibrations. Sound is merely the debris in a medium moving in yet otherwise and your strategies analyzing it for you. So no, it won't be able to be grew to become into something. Sound isn't an merchandise, yet greater of your strategies's interpretation of a vibration technique. understand? Now, can the vibrating debris in a medium be harnessed into electric ability? perhaps, yet you could choose lots of it. we've dashing water's strikes transforming into electricity, in spite of each thing. yet we could choose plenty sound, plenty vibration, that it does not possibly be seen merely sound waves at that element. greater like, powerful, familiar microwaves.

Answer 4

With a microphone and an LED. You will need either a really loud sound or an amplifier though.

Ha ha Cirric, beat you to it!
