This has to be one of the most engaging light modulation demos ever! The Light Modulator is an easy-to-use, plug-and-play demonstrator of light and physics principles that will leave your students in awe. Plug the flashlight transmitter into a cell phone, play a song, and the sound will "ride" the light beam to the solar panel receiver! Ten unique experiments are provided. You'll be teaching concepts such as amplitude modulation, AC vs DC, fiber optics communication, persistence of vision, molecular kinetic theory, light properties, the Inverse Square Law and more. Requires 3 AAA and 2 AA batteries and a cell phone or MP3 player.
Here's how it works:
The phenomenon is known as , the same as the AM on your radio! You now have the ability to transmit sound (information) on a carrier (light) beam! We have fine-tuned and re-designed this technology into this easy-to-do kit for all science teachers and science demonstrators. All you need is your mobile phone and you're ready to amaze...Kit includes:
