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 a radio signal to reach Saturn from earth?
4'000'000'000'000'000'000'000'000'000'000 years
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 would it take for a radio signal from earth to reach Venus?
at a rough guess, i,d say 2 minutes as it,s our nearest neighbour
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'

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?
About 2.54 million years

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.
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!
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.
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.
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?
*Homework question* The speed of light (c) is about 300,000 kps. So (382,000,000 / (c*1000)) * 2 = <Answer>
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.
