Answer:
[tex]\lambda=0.57m[/tex]
Explanation:
The distance traveled by the sound wave between the beats of the wing is its wavelength, since it is defined as the distance traveled by a periodic disturbance that propagates in a cycle, is defined as:
[tex]\lambda=\frac{v}{f}[/tex]
Where v is the speed of sound and f the frequency of the wing beats
[tex]\lambda=\frac{340\frac{m}{s}}{600Hz}\\\lambda=0.57m[/tex]
