I've heard that em wave consists of mutually perpendicular electric & magnetic oscillations.
Imagine that I've a unit charge at any point in space. Associated with this charge, there exists an electric field which diminishes with distance from the charge. If we set forth an oscillation in this field, it can get transmitted. But since the field strength is getting diminished wrt distance, How can the oscillation get transmitted indefinitely?
