Answer: 6.29 meters.
Explanation:
The formula to find the wavelength is given by :-
, where v is the speed of wave and f is the frequency of wave.
We are given that ,
The speed of sound is 346 m/s.
i..e v=346 m/s
A sound wave travels at a frequency of 55 H.
i..e f=55 Hz
Then, the wavelength =


Hence, the wavelength would be 6.29 meters.
