When a vehicle passes, TV reception gets distorted. This is because
Metal reflects radiowaves
Spark plug creates electromagnetic disturbances
Vehicle pollution affects the performance of the TV components
Modern vehicles use electroignition system
Spark plug creates electromagnetic disturbances
This is caused due to the interference caused by the electromagnetic waves generated by a passing vehicle. These waves were within the same frequency range as that of the waves of TV reception and hence caused Interference. interference is a phenomenon in which two waves superimpose to form a resultant wave of greater or lower amplitude. Interference usually refers to the interaction of waves that are correlated or coherent with each other, either because they come from the same source or because they have the same or nearly the same frequency. Interference effects can be observed with all types of waves, for example, light, radio, acoustic, and surface water waves and due to the interference caused by the vehicle electromagnetic disturbances occurs in the TV reception and gets distorted.
