Radio waves and light are the same thing (electromagnetic radiation), so yes, they travel at the speed of light.
The reason we can't "see" radio waves is because their frequency is much lower than visible light.

No, radiowaves will not go as fast as the speed of light. Light travels at 300,000 kilometers every second! It can travel to the Moon in just over a second, to the Sun in eight minutes, and even to distant Pluto in about 5 hours.
Radio waves, on the other hand, are sound energy, and even though they can travel in space, it's slower, being 6 hours or more.

Yes, in a vacuum, all electromagnetic emissions travel at the same speed. In other media, they tend to be a little slower but for a reason other than a slowing of the actual speed of the electromagnetic wave. As waves cross boundaries between different media, their speeds appear to change while their frequencies remain constant.
When electromagnetic radiation travels through denser substances, it is continually being re-absorbed and re-emitted fractions of a second later by individual atoms. That, not a change in speed of light, accounts for the slower measured speeds.

Yes, a radiowave is just a different frequency from visible light. They are both classified as electro-magnetic radiation and travel at the same speed through space.

Since radio waves are a part of the electromagnetic spectrum, which includes light, they travel as fast as light. That would mean our first radio communications have traveled about 100 light years from Earth.

Yes they travel at the same speed but only in vacuum!
In air there speeds vary to a very negligible defference.
They travel at the same speeds because both are electromagnetic waves and belong to the electomagnetic spectrum. All waves in electromagnetic spectrum travel at the same speed that is the speed of light.

yes,they move at the same speed.all electromagnetic waves travel at the speed 3*10^8 m\s.look up on the electromagnetic spectrum.

Yes, radio waves travel at the speed of light. In fact, radio waves ARE light. They are just very, very long wavelength light.

Radio waves will travel as fast as the Medium they are travelling in will permit.

just in vacum yes, but if in the another medium not because the length of the wave is diferent
