Plane microwaves from a transmitter are directed normally towards a plane reflector. A detector moves along the normal to the reflection. Between positions of 14 successive maxima, the detector travels a distance 0.14m. If the velocity of light is 3 xx 10^(8) m//s, find the frequency of the transmitter.
