A radio transmitting station operating at a frequency of 120 MHz has two identical antennas that radiate in phase. Antenna B is 9.00 m to the right of antenna A . Consider point P between the antennas and along the line connecting them, a horizontal distance x to the right of antenna A . For what values of x will constructive interference occur at point P ?
