Light & radio waves are essentially both electromagnetic radiation, just different frequencies - and they both travel at the same speed.

Light and radio waves are both electromagnetic forms of energy and thus travel at the same speed. Has nothing to do with how far away the star is.

Light and radio waves are the same phenomenon, but at different frequencies. Thus radio and light travel at the same speed.

Light waves and radio waves are part of the electromagnetic spectrum so they travel at the same speed.

Radio waves I think travel at the speed of sound. If it takes 20 Years to travel at the sped of light to get to The Star, then it would take about 340mps x 6 trillion x 20. This would get you
4.08 x 10^12 I think. I personally have not a 100% clue but I think this would be a good guess.

Same speed. Light & electromagnetic energy have the same speed limit (Einsteinian)

you obtain that the incorrect way around! your eyesight does not shuttle it is the easy that does. in case you seem at a celeb that's one hundred million easy years away the celeb which you notice is a picture that's one hundred million easy years previous. it is because of the fact it has taken one hundred million easy years for the easy to get to you so that's obtainable that the celeb now no longer exists!

All photons travel at lightspeed in vacuum as viewed by all inertial observers.
