SA MEDAN G3 NESYA PUTRI AYU – STRING TELEPHONE

The project attempts to investigate how sound travels through air by way of creating a string telephone. A string telephone works very much like a landline phone. When you talk into the cup your voice sends sound waves inside the cup, vibrating the bottom of the cup. The vibrations are transferred to the string, across the string and into the bottom of the other cup. The sound waves become vibrations inside the second cup, transferring the sound of your voice.
