how electromagnetic waves produced
Answers
Answer:
Electromagnetic waves are created by oscillating charges (which radiate whenever accelerated) and have the same frequency as the oscillation. Since the electric and magnetic fields in most electromagnetic waves are perpendicular to the direction in which the wave moves, it is ordinarily a transverse wave.

Electromagnetic waves are created by oscillating charges (which radiate whenever accelerated) and have the same frequency as the oscillation. Since the electric and magnetic fields in most electromagnetic waves are perpendicular to the direction in which the wave moves, it is ordinarily a transverse wave.
The strengths of the electric and magnetic parts of the wave are related by \(\frac{E}{B}=\text{c}\\\),
which implies that the magnetic field B is very weak relative to the electric field E.
