Describe the process by which an electromagnetic wave is produced. A. An electrically charged particle vibrates, producing only an electric field that moves.
B. An electrically charged particle vibrates, producing electric and magnetic fields.
C. A magnetic field and an electric field collide, producing energy and light.
D. Radio waves break down into smaller wavelengths, producing new waves.
