Explain how our tin can phone works. Start with the vocal cords of the speaker and end with the eardrum of the listener. Use terms from our definitions in your explanation and relate the topic to our study of waves.

When a person talks into the cup, the voice produces acoustic energy that tunnels sound waves into the cup, causing the bottom of the cup vibrates back and forth. forcing the sound waves into the string. The string then begins to vibrate, causing a transverse sound wave to travel to the other cup. The bottom of the second cup begins to vibrate in response, producing the same sound waves that the person can hear.
