how long do radio waves to get to venus from earth
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.t 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.
