Which would be the first to reach Earth if a light signal and a radio signal were emitted from a star?
It would be a tie; both light and radio are electromagnetic waves, as are X-rays, gamma rays, ultra-violet and infrared. They all travel at the same speed, the "speed of light", which is about 300,000 km/second, or 186,000 miles per second.
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?
The answer is right there in the words of the question. Radio and light are the same physical phenomenon, and they travel at the same speed. The star is 5 light years away. That means the distance that light ... and radio ... travel in five years. It takes light from the star 5 years to reach us, and it takes radio from us 5 years 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 many hours are required before a radio signal from a space probe near Pluto reaches earth 6.00x10 to the power of 3 km. away?
To calculate the time it takes for a radio signal to travel from a space probe near Pluto to Earth, we can use the speed of light, which is approximately 299,792 km/s. Given the distance of 6,000 km, the time can be calculated using the formula: time = distance/speed. Thus, time = 6,000 km / 299,792 km/s, which is approximately 0.020 seconds. Therefore, it takes about 0.020 seconds for the radio signal to reach Earth.

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.
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.
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

Why do radio waves change to another wave to reach a satellite in space?
Radiation can move through space because it is made up of light. Unlike sound, it doesn't need a medium (something it can go through) and it can travel through the vacuum. Only light can do this, and radiation can also move through air, obviously.

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.
How long would it take for a signal to travel from a star located 100 light years away to reach Earth in Earth years?
It would take 100 Earth years for a signal to travel from a star located 100 light years away to reach Earth.
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!
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.
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.
