Answer the following question given this paragraph: 

24.2 Production of Electromagnetic Waves • 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.


Q: What are  electromagnetic waves created by?


A:
oscillating charges
