A radio signal would take eleven years to reach a star that is eleven light years away. This is because the speed of light is the fastest speed at which any form of information can travel through space.

∙ 13y ago11 years since a radio signal is an electromagnetic wave, just as light is, and electromagnetic waves travel at the same speed.

Which would be the first to reach Earth if a light signal and a radio signal were emitted from a star?
The light signal would reach Earth first because light travels faster than radio waves in a vacuum. In space, light travels at the speed of approximately 186,000 miles per second, while radio signals travel at the speed of light.
How long does it take for Voyager 1's radio signal to reach earth from the Heliosphere at the edge of our solar system?
At the moment - according to the Wikipedia article (see related link) it takes about 16 hours for signals sent from Voyager to reach Earth. At least that's what it says in the section titled 'Current Status'
How do you figure out how many sec min hrs it takes for a radio wave to reach a star that is 5 light years away?
You can calculate the time it takes for a radio wave to reach a star using the speed of light, which is approximately 186,282 miles per second. Since the star is 5 light years away, you would multiply 5 by the number of seconds, minutes, or hours in a year (31,536,000 seconds, 525,600 minutes, or 8,760 hours) to find the time it takes for the radio wave to reach the star.
How long does it take a radio signal to reach Saturn from earth?
It takes about 1 hour and 24 minutes for a radio signal to travel from Earth to Saturn when the two planets are at their closest point. This distance can vary depending on the positions of the two planets in their orbits.
How long would it take for a radio signal from earth to reach Venus?
It takes about 5 minutes for a radio signal to travel from Earth to Venus when they are closest to each other in their orbits. Venus is approximately 38 million kilometers away from Earth at its closest point.

A space probe on the surface of mars sends a radio signal back to the earth, a distance of (9.03*10^7 km). Radio waves travel at the speed of light (3.00*10^8 m/s). How many seconds does it take for the signal to reach the earth?
0.301 seconds
How many years would it take for a radio signal to reach the Andromeda galaxy?
It would take approximately 2.5 million years for a radio signal to travel from Earth to the Andromeda galaxy, which is about 2.5 million light-years away.
Why do radio waves change to another wave to reach a satellite in space?
Radio waves are electromagnetic waves that can travel through space, but they can get weaker over long distances. To reach a satellite in space, the radio waves need to be amplified or relayed to maintain strength. The satellite acts as a receiver and retransmits the signal back to Earth, allowing for communication over long distances.

If a volume knob has high resistance is the radio's volume loud or low?
If a volume knob has a high resistance, then the radio's volume would be low because more of the electrical signal would be resisted and not reach the amplifier and thus not reach the speakers.
Radio waves carry a blank from a station to your home?
The signal is transmitted by way of electromagnetic radiation, the same type of energy that, within the visible spectrum, makes up light. The signal can maintain an analog profile, or the signal can be transmitted digitally, but the energy form is the same. However it is transmitted, the radio converts the signal to sound by way of the speaker elements to your ear.
What is the distance that a ham radio can travel?
The radio signal can travel to the moon, bounce off its face, and reach an operator on the other side of the world. You can even talk to the International Space Station!
The moon is 382000000 m from earth how long does it take a radio signal to reach the moon and back to a reciver on earth show your work?
The time it takes for a radio signal to travel from Earth to the moon and back can be calculated using the formula: Time = Distance / Speed of Light. The speed of light is about 299,792 kilometers per second. So, Time = (382,000,000 * 2) / 299,792 = 508.8 seconds. Therefore, it takes approximately 508.8 seconds for a radio signal to reach the moon and return to Earth.
What is propagation delay time?
It's the time it takes a radio signal to travel from one place to another, the time it takes a light beam to travel from one end of the fiberoptic cable to the other end, the time it takes an electrical signal to travel from one side of a circuit board to the other side, etc., things like that. If you're listening to the baseball game on the radio, it doesn't much matter how long it took the signal to reach you from the transmitting tower. But if the radio signal is being used to control a high-speed passenger train, or a drone aircraft on a counter-insurgency mission, or a robotic rover digging in the dirt on Mars, then the time it takes the radio signal to get there does make a difference.
How long does it take a radio signal from the Voyager spacecraft to reach Earth if the distance between Voyager and Earth is 4.16 109 km?
The speed of light is about 300,000 km/sec. Just divide the distance by the speed of light. The answer will be in seconds; divide by 60 to get minutes, by 3600 to get hours, or by 86400 to get days.
