Answer:A wave has a wavelength λ, which is the distance between adjacent identical parts of the wave. The wave velocity and the wavelength are related to the wave's frequency and period by vw=λT or vw=fλ.
Explanation:
Answer:
7.39 m or 3.61 m
Explanation:
= Wavelength
f = Frequency = 90 Hz
v = Speed of sound = 340 m/s
Path difference of the two waves is given by

Velocity of wave


So, the location from the worker is 7.39 m or 3.61 m
It increases, because the centripetal acceleration is inversely proportional to the radius of the curvature.
Hopr it helps :)
