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 1 m. Can you explain the phenomenon observed by the student. Select one: a. The student is moving between the nodes and antinodes of the electromagnetic wave carrying the signal. b. Electrostatic field produced by the student is interfering with the TV signal. c. Electrostatic field produced by the student intefreres with the aerial. Clear my choice
