The wavelength of the sound wave is 0.24 m
Explanation:
First of all, we calculate the speed of the wave, which is the ratio between the distance covered by the wave and the time taken:
where, for the wave in this problem
d = 91.4 m
t = 2 s
Substituting,
Now we can find the wavelength of the wave by using the wave equation:
where
v is the speed of the wave
f is its frequency
is the wavelength
For the wave here,
f = 192 Hz
v = 45.7 m/s
Solving for the wavelength,
