Two radio antennas A and B are placed 10.0 [m] apart as shown. They coherently emit identical radio waves with wavelength of 4.00 [m]. A detector (red dot) is initially placed at point O, a distance y above antenna B, where it registers the occurrence of m=+1 maximum. The detector is then moved along a straight line OP to a new location P that is directly to the right of antenna B. If the detector again registers m = +1 maximum at P, what is the distance between points O and P? 10.0 m B O A 5.70 m OB. 6.12 [m] O C. 10.9 [m] OD. 12.6 [m]
