Question

longitudinal standing waves are related to the resonance of which of the following instruments?

a) bowed instruments

b) percussion instruments

c) string instruments

d) woodwind instruments

Answer 1

1. String Instrunments: One "container" that works very well to produce standing waves is a thin, very taut string that is held tightly in place at both ends.Since it is held tightly at both ends, that means there has to be a node at each end of the string. Instruments that produce sound using strings are called chordophones, or simply strings.

2. Woodwind instrunments: Another great container for standing waves actually holds standing waves of air inside a long, narrow tube. This type of instrument is called an aerophone, and the most well-known of this type of instrument are often called wind instruments because, although the instrument itself does vibrate a little, most of the sound is produced by standing waves in the column of air inside the instrument.
