What is the speed of a satellite signal?
The speed of a satellite signal is approximately the speed of light, which is about 299,792 kilometers per second. This means that signals transmitted from a satellite to Earth or vice versa travel at this high speed.
What is the difference between radio horizon and optical horizon?
radio signal bents around the curvature of earth and hence travel longer distance than the line of sight signal. At ultra high frequencies signal follows the line of sight path and hence maximum communication distance is limited due to curvature of earth for given height of transmitting and receiving antenna
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.
How long does it take a radio signal from the Voyager spacecraft to reach Earth if the distance between Voyager and Earth is 3.03 109 km?
Distance = 3.03 x 109 kmSpeed of radio = 3 x 108 m/s = 3 x 105 km/sTime = (distance)/(speed) = (3.03 x 109)/(3 x 105) = 1.01 x 104 seconds = 2hrs48.3min (rounded)
How did the Apollo 11 picture make it to earth?
if you are asking about the live television footage, the signal was sent via radio waves from an antenna on the LM and received by the Parkes radio telescope in Australia. If you are asking about the still pictures, they were brough home by the astronauts and developed on site at NASA.
How is automatic gain control bias voltage developed in a valve superhet radio reciver circuit?
The signal is changed to dc in the AGC circuit to change the gain. A weak signal will increase gain.
What region of atmosphere helps radio broadcasters?
The Ionosphere hels AM radio broadcasters by reflecting the signal back to Earth.
Why are radio stations enhanced when you touch a antenna?
Because you 'earth' it and the signal travels through you.
What is the speed of a satellite signal?
The speed of a satellite signal is approximately the speed of light, which is about 299,792 kilometers per second. This means that signals transmitted from a satellite to Earth or vice versa travel at this high speed.
If a spacecraft is approaching the earth relative to the radio signals it send out the signal received on the earth have?
Shorter wavelength, higher frequency.
How radio signal works?
Your radio signal works by using its signal to go to a tower and back to your radio (Via antenna).
what is Speed of a radio wave?
Radio waves can travel 300,000km per second. If someone was dialing from the moon to the earth, a signal would arrive in about 1.3seconds. The distance from the moon to the earth is 390,000km.
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 the difference between radio horizon and optical horizon?
radio signal bents around the curvature of earth and hence travel longer distance than the line of sight signal. At ultra high frequencies signal follows the line of sight path and hence maximum communication distance is limited due to curvature of earth for given height of transmitting and receiving antenna
How can you get radio signal from space on your cmputor?
You can get a radio signal from space on your computer using SETI.
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 long would it take to send a radio signal from Earth to a spacecraft that's 900 million meters away?
It would take approximately 3 seconds for a radio signal to travel from Earth to a spacecraft that is 900 million meters away. This is because radio waves travel at the speed of light, which is approximately 300 million meters per second.
