2 minutes and 7.25 seconds
The speed of light (and thus radio waves) is 3x10^8 m per second. So if the planets are 401million km apart, that makes it 1337 seconds, or just over 20 minutes. And if the planets are closest together, light would take 183 seconds, slightly more than 3 minutes. At its closest Mars is about 35million miles away. At its most distant it is about 230 million miles away. The speed of radio waves is 186000 miles per second so at its furthest the radio waves will take about 20minutes to get there. Work it out on a calculator for greater accuracy. The distances to be traveled are so great that even light or radio waves take a while getting there. It takes around eight minutes for radio waves to travel from the Earth to the Sun, and four years to get from here to the nearest star. Actually, radio waves travel very quickly through space. Radio waves are a kind of electromagnetic radiation, and thus they move at the speed of light. The speed of light is a little less than 300,000 km per second. At that speed, a beam of light could go around the Earth at the equator more then 7 times in a second. How long does it take for radio or light waves to travel from Earth to Jupiter, Saturn, Uranus, Neptune and Pluto? up vote 3 down vote favorite. I know it roughly takes 20 minutes from Earth to Mars, and 8 minutes from the Sun to Earth, but don't know how long for the other planets on my list. planets solar-system light. Radio waves travel at 186,282 miles per second. Divide the distance to Venus by the speed of the radio waves: 30,000,000 / 186,282 = 161 seconds 161 seconds divided by 60 to convert into minutes: 161 / 60 = 2.6 minutes On average it takes a radio wave 161 seconds (2 minutes 41 seconds) to travel from Venus to Earth. At the closest distance, Venus is about 23.7 million miles away from Earth, and radio waves, in a vacuum travel the speed of light (about 186,000 miles per second) so therefore it would take a radio wave about 127.42 seconds -- 2 minutes and 7.25 seconds to get to Venus from Earth. XpretenderX · 6 years ago. Report Abuse. Radio waves travel at the speed of light one hundred and ninety million miles per second. A radio wave sent to Mars will take about four minutes to get there, and the return message will take four minutes, eight minutes both ways. It takes the light from the sun eight minutes to reach th earth, if the sun was to go out, it would be eight minutes until you will know it has gone out. At its closest Mars is about 35million miles away. At its most distant it is about 230 million miles away. The speed of radio waves is 186000 miles per second so at its furthest the radio waves will take about 20minutes to get there. Work it out on a calculator for greater accuracy. With that said, calculating the radio delay between Earth and Venus -- the closest planet to Earth -- is now simply a math problem. However, the distance between Venus and Earth varies throughout the year of each; at its closest, Venus is about 38 million km from Earth, and about 261 million km at its farthest. One major problem with intrasolar and interstellar communication is the vast distances involved. On Earth, radio communication is all-but instantaneous, because radio waves travel at the speed of light, approximately 300,000 kilometres per second. How long will it take for a radio wave to travel 100km if the speed of radio waves is 3x108metres per second? If the speed of radio waves, also known as the speed of light, is 3x108 metres per second, then it is also 3.333 nanoseconds per meter. (Simply invert) As such, the wave would … take 333.3 microseconds to traverse 100 kilometres. How long does it take a radio message to travel to the moon from the earth? It's roughly 1-1.5 seconds. Light (and radio) travel at 186,000 miles per second, and the moon is usually about 230,000 miles away. At their closest, Venus and Earth are 40 million kilometers from each other. At the speed of light, 3 x 108 meters per second, that distance could be traversed in slightly ove … r two minutes. At the furthest, Venus and Earth are 257 million kilometers from each other. At the speed of light, that distance can be traversed in slightly over 14 minutes. Venus has an orbit of about 108 million kilometers (67 million miles) from the Sun. The closest approach of about 39.5 million kilometers (23.6 million miles) would be with Venus at its farthest from the Sun and Earth at its closest. Radio waves travel at essentially the speed of light in space, and that is a known value. So if you know the exact distance between Earth and Pluto, you can divide the distanc … e by the speed to see how long a radio signal from Earth will take to reach there. How long does it take a radio message to travel to the moon from the earth? It's roughly 1-1.5 seconds. Light (and radio) travel at 186,000 miles per second, and the moon is usually about 230,000 miles away. · just now. Report Abuse.
