Where in space are the radio waves that were cast 100 years ago?

Radio waves travel at the speed of light, so radio waves broadcast 100 years ago that were strong enough to reach into space are 100 light-years away.


Where are radio waves faster-earth or space?

Radio waves travel with the highest speed in vacuum, and slightly slower in air. So they move slightly faster in space than on earth.


How fast do radio waves travel in a empty space?

Radio waves travel at the speed of light, approximately 300,000 kilometers per second, in empty space.


Are The speeds of X rays and radio waves in outer space are different?

No. In vacuum, all electromagnertic waves have the same speed.


What is the link between radio waves and visible light?

Both are electromagnetic waves travelling at a speed about 300,000 km in one second in free space or in air medium. But radio waves have longer wavelength compared to that of light waves.


How does the speed of radio waves compare with the speed of infrared waves?

Radio waves travel at the speed of light, which is the fastest speed possible in a vacuum. Infrared waves also travel at the speed of light, so both types of waves travel at the same speed.


Do particles in the atmosphere slow down either the speed of light or radio waves as they travel outward into the universe?

Light and radio waves travel slower through air than they do through space or vacuum. But as soon as they leave the atmosphere and get into space or vacuum, they speed up to 299,792,458 meters per second.


Is the speed of radio waves greater then visible waves?
