Quizplus · Accepted Answer

Wireless radio signals travel at the speed of light, which is approximately 186,000 miles per second. They do not require an atmosphere to move, as they can travel through a vacuum. They also do not travel as discrete particles. While they are a form of electromagnetic radiation, they are not visible light, which is only one small portion of the electromagnetic spectrum.
