How long does it take for a radio signal to reach Saturn?
around 83 minutes
How long does it take a radio signal to reach the moon?
Radio waves propagate in vacuum at the speed of light c, exactly 299,792,458 m/s. Propagation time to the Moon and back ranges from 2.4 to 2.7 seconds, with an average of 2.56 seconds (distance from Earth to the Moon is 384,400 km).

Do radio waves go on forever?
The earliest radio waves emitted from earth are currently about 200 light years away. However as mentioned before they will keep going forever getting harder and harder to detect as time passes. They will travel forever radiating from the Earth at the speed of light.
How many minutes does a radio signal need to travel?
Do radio signals travel at the speed of light?
Radio waves travel at the speed of light, which is approximately 186,000 miles per second.
How long does it take for a signal to reach Mars?
All communication between Mars and Earth goes through satellites. Because of the distance, there is a substantial delay. As communication signals travel at the speed of light, this means that it can take between 3 and 22 minutes for the information to reach the other end, so a phone call would not be practical.
How long does it take to send a radio signal to Mars?
about 5 to 20 minutes
How long will the trip to Mars take?
about 21 months
How long would it take a radio signal to travel 500 million light years?
Telescopes in Canada detected mysterious radio signals in a pattern repeating every 16.35 days. We asked a former Colorado professor to explain what they are. DENVER — An array of telescopes in Canada recently discovered a series of repeating radio signals from a galaxy about 500 million light-years away.

How long does it take a signal to reach a satellite in low Earth orbit?
To keep transmitted power requirements low, both the satellite and the earth station antennas must be highly directional. Furthermore, for LEO satellites, orbital periods are of the order of 90 minutes, which means that satellites will only be visible from 5 to 20 minutes per orbit (depending on altitude).
Do radio waves decay in space?
Does the radio signal decay when it travels through the intergalactic space? When you emit the radio signal it starts moving at the speed of light. Radio beam is diffusing with each kilometer the signal has traveled. … But if the receiver is far away, the signal will become weaker and weaker until it becomes a noise.
Do radio waves pass through our bodies?
There’s nothing in the body corresponding to radio waves, and for the most part they pass right through you. Water can capture a microwave and spin; that’s how microwaves heat food. Skin evolved for the purpose of capturing and reflecting light, to prevent it from being absorbed by more sensitive components inside.
