WebHigher frequency waves are able to pass through the atmosphere entirely and reach the ground. This process also works in reverse for radio waves produced on the earth. The high frequency waves pass through the ionosphere and escape into space while the low frequency waves reflect off the ionosphere and essentially "skip" around the earth. Light travels through the vacuum of space at 186,828 miles per second as transverse waves, outside of any material or medium, because photons—the particles that make up light—also behave as waves. This is referred to as the wave-particle duality of light. See more The wave-particle duality of light simply means that light behaves as both waves and particles.
