Question

You are listening to an "A" note played on a violin string. Let the subscript "s" refer to the violin string and "a" refer to the air. Then:

a) fs = fa but λs ≠ λa
b) fs = fa and λs = λa
c) λs = λa but fs ≠ fa
d) λs ≠ λa and fs ≠ fa
e) linear density of string = volume density of air

Answer 1

a) fs = fa but λs ≠ λa
The wavelength of the string is the length of the string, while the wavelength in air is the speed of sound in air divided by the frequency.
