What are 3 facts about radio waves?
Despite their versatility, radio waves have lower frequencies than those of microwaves.
- Their signals are bounced through the atmosphere. Actually, radio waves are shot straight into a part of the atmosphere called the ionosphere.
- Radio waves bounce forever if not absorbed.
- Radio waves can travel forever.
What are 2 facts about radio waves?
