0.73 meters
Explanation:
Wavelength of sound in this case,
Now,consider an arch of a circle,where those two points are present with an angular separation of
So,the radius of the circle is the wavelength of sound,as sound goes to these two points which creates this phase difference.
Now,considering the arch to be very small,we can say length of the arch=distance between those two points=
Now as r=
Distance comes out to be
Or,0.73 meters
