A student is watching a TV that is receiving a signal though an in-house dipole aerial. As the student stands up and walks towards the TV he can observe that the signal gradually degrades and then recovers again. The students walks back and forth to discover that the distance between the points where the best and the worst signals are observed is 0.9 m. Calculate the frequency of the signal TV is receiving given that the velocity of the wave is 3 x 10 km/s. Give your answer in mega-Hz (MHz).
