Answer:
0.6275 metres
Explanation:
v = fl
125.5 = 200 * wavelength
125.5 / 200 = wavelength = 0.6275m
The speed of a sound wave does not depend on the frequency of the wave, but only on the properties of the medium.
Since we are in the same concert all, the medium of propagation is still the same (the air), so it has not changed; therefore, the speed of the sound wave has not changed, and it is still 344 m/s.
So, the correct answer is "344 m/s".
