Passage says " The 4 strings of a violin all have the same length of roughly 12 inches. in an experiment students studied the 4 strings of an old violin and the four strings produced these frequencies
string I : 196 Hz
string II: 294Hz
string III: 440 Hz
string IV: 659 Hz
The question asks " The wavelength of a standing wave on each string is "
A. 0.326m for all strings
B. 0.652m for all strings
C. 1.73m 1.16m 0.77m 0.52m for strings I through IV
D. 3.46m 2.32m 1.54m 1.04m for strings I through IV
Answer is B and explanation says The fundamental wave is associated with the fundamental frequency of the string. There are no nodes between the endpoints of the string in the fundamental node so the string is half a wavelength long.
I don't understand this? why did they use the fundamental wave ?
Thanks!
