Question

When a low flying aircraft passes over head, we sometimes notice a slight shaking of the picture on our TV screen. This is due to

Diffraction of the signal received from the antenna.
Interference of the direct signal received by the antenna with the weak signal reflected by the passing aircraft.
Change of magnetic flux occuring due to the passage of aircraft
Vibration created by the passage of aircraft

The correct answer is: Change of magnetic flux occuring due to the passage of aircraft
