Which of the following statements about electromagnetic waves is true?
Step 1: Understand what electromagnetic waves are. They are waves that consist of electric and magnetic fields oscillating perpendicular to each other.
Step 2: Learn that electromagnetic waves do not need a medium (like air or water) to travel. They can move through empty space.
Step 3: Know that electromagnetic waves travel at the speed of light when in a vacuum, which is approximately 299,792 kilometers per second.
