Data sheet Signal and information set


Thanks to the model, the student understands that a sound is a signal containing information. It also understands that a light wave can carry a signal.
Using a tablet for example as a sound source, the experience becomes concrete. A student injects a sound of its own selection while another student checks the sound reception with headphones. Thus, they do not disturb the rest of the classroom.

Other experiments are possible: use a low frequency function generator or an oscilloscope for more quantitative results.
