How Do Radio Waves Travel Around The World . You’ll find am radio waves traveling in this manner for short to medium distances, which is why you can still hear radio signals even when there isn’t a transmitter and receiver in your line of sight. Some of the transmitted waves travel along the ground and follow the curvature of the earth.

The speed is much faster than the 1,125 feet (340 meters) which sound moves through the air. Heinrich hertz proved the existence of radio waves in the late 1880s. As like all other electromagnetic waves the radio waves also travel at the speed of light.

Radio waves travel at the speed of light, which is approximately 186,000 miles per second. Some radio frequencies that have very high wave cycle rates, or frequency, tend to travel in straight lines without being affected much by the atmosphere. Radio waves are a kind of electromagnetic wave whose wavelength falls in the electromagnetic spectrum. Top frame shows how most media works, etc., would illustrate it:

This is known as modulation. Actually, radio waves travel very quickly through space. The method of travel, or propagation, is determined mostly by the frequency of the radio wave. They are not strongly absorbed by the atmosphere. These radio signals ‘bounce’ off the ionosphere and return to land, where they are received by.
