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 × 105 km/s. Give your answer in mega-Hz (MHZ).

Question
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 × 105 km/s.
Give your answer in mega-Hz (MHZ).
