Question:
How does resonance (sound waves in particular) effect the physical characteristics of objects?


Replies:
Michael: resonance will not usually have any visable effects on physical characterisitcs, however, sometimes it can be devistational. Use your local library to look up the "Tacoma Narrows Bridge" , or if you have access to "The Mechanical Universe" video tape series, there is an entire video on resonance and the like.

A sound wave is a vibration that travels through the air and through objects. When a wave reaches a surface of an object, some of the wave is reflected and some passes through into the object. Normally, very little of the wave remains within the object for very long. When the wave vibrates at a rate natural to the object, much of the wave remains within the object. As more waves like this enter the object, vibration builds up enough to distort or break the object. An example can be done with a Slinky. Hold it at both ends. If you shake an end at a natural rate, the Slinky will over time develop a very large vibration. If you do not, much of the vibration will be felt passing into the hands that hold the spring.
