Problem 11DQ

Children make toy telephones by sticking each end of a long siring through a hole in the bottom of a paper cup and knotting it so it will not pull out. When the spring is pulled taut, sound can be transmitted from one cup to the other. How does this work? Why is the transmitted sound louder than the sound travelling through air for the same distance?

Step-by-Step Solution:

Solution 11DQ Step 1: When we talk,our vocal cords make molecules in the air vibrate.those vibrating air molecules make other air molecules around them vibrate,and so on,which is how sound travels through the air. Examples of sources of sound,such as guitar,violin or piano strings are good examples of how vibrations can generate the sound. Step 2: In this activity,your voice vibrated the air inside of the cup,which in turn made the bottom of the cup vibrate.these vibrations are transferred to the strings and then into the bottom of your partner’s cup,which made the air inside of the his cup vibrate and become detectable sound.
