Question

Two transmitting antennae, identical in every way, are broadcasting a pure carrier wave of 100.0 MHz. The antennae are separated by 120 m. You are far away (...5.0 km ...) , sitting at a first minimum in the interference pattern. The antennae, both on huge moving platforms, move toward each other with a relative speed of 5.6 m/s. How fast must you be moving, at t = 2.0 sec, to stay with the first interference minimum ? (...think small angle approx ! ...)
