Final answer:
Both electric and magnetic fields are disturbed as an electromagnetic wave passes.
Step-by-step explanation:
As an electromagnetic wave passes, both an electric field and a magnetic field are disturbed or vibrate. The changing electric and magnetic fields in light create disturbances that travel rapidly outward from the point of origin and can use their energy to disturb other things farther away. For example, the radiation generated by a transmitting antenna full of charged particles and moving electrons can, sometime later, disturb a group of electrons in your car radio antenna and bring you the news and weather while you are driving.
