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 distance by the speed to see how long a radio signal from Earth will take to reach there. Of course, during the year the time will vary, because the distance will vary.
Average distance of Pluto from the Sun: 5.874 billion kilometers
Average distance of Earth from the Sun: 149.6 million kilometers
Distance from Earth to Pluto ~ 5.724 billion kilometers
Speed of radio signal (light): 299792.456 kilometers per second
Dividing: 5.724 x 109 / 2.998 x 105 = 1.91 x 104 seconds = 5.3 hours
(and of course, to send it and receive a reply would take twice that time)
---
Absolute closest distance (4.285 billion km) -- 4.0 hours
Absolute farthest distance (7.463 billion km) -- 6.9 hours

What layer of the atmosphere reflects radio waves?
The ionosphere is the layer of the atmosphere that reflects radio waves. This layer is able to reflect specific frequencies of radio waves back to Earth, allowing for long-distance communication using radio signals.
This layer is responsible for the possibility of radio communication?
The ionosphere is the layer responsible for enabling long-distance radio communication by reflecting radio waves back to Earth. Its charged particles interact with radio waves, bending and reflecting them to facilitate communication over long distances. Without the ionosphere, radio waves would continue into space, limiting long-distance communication possibilities.
Pluto how many time needed to rotate on its axis?
Pluto rotates much more slowly than Earth so a day on Pluto is much longer than a day on Earth. A day on Pluto is 6.4 Earth days or 153.3 hours long.
Is Earth's day longer than Pluto's day?
No, Earth's day is shorter than Pluto's day. A day on Earth lasts about 24 hours, while a day on Pluto lasts about 6.4 Earth days.
What is the longest wavelengh in the electromagnetic spectrum?
The electromagnetic waves with the longest wavelength are called "radio waves". There is no limit to how long the wavelengths can be.
What happens when radio waves hit the earth?
When radio waves hit the Earth's atmosphere, they can be absorbed, reflected, or refracted. Some radio waves may continue through the atmosphere and reach the Earth's surface, where they can be picked up by antennas and receivers for communication or broadcasting purposes. The Earth's atmosphere allows radio waves to travel long distances without much degradation, making them valuable for long-range communication.
What layer of the atmosphere reflects radio waves?
The ionosphere is the layer of the atmosphere that reflects radio waves. This layer is able to reflect specific frequencies of radio waves back to Earth, allowing for long-distance communication using radio signals.
How Do sunspote relate to the incidence of radio and tv disturebances?
The radiation emitted by sunspots ionizes the upper layers of the Earth's atmosphere. When that happens, radio waves (TV & radio) refract (bend) more in the ionization rather than shoot off into outer space as much. The radio waves by bending back to Earth travel much farther than if they just went straight. In the right conditions, these bent radio waves can bounce up off the Earth's surface and refract again in the ionized layers of the atmosphere, coming back down. In this ways, radio waves can travel long distances. The result is, that these long-distance radio waves come back to Earth where there are other radio and TV stations using the very same frequencies, and the long-distance radio waves interfere with the local programing.
How do very long radio waves reach stations beyond the curvature of the Earth?
Radio waves, like all forms of electro magnetic radiation are affected by gravity, so the Earth's mass helps to bend the radio waves to an extent. Beyond that, radio waves can be reflected naturally by atmospheric conditions, but generally, when a radio signal needs to be transmitted a significant distance, it is done by a series of radio towers in relay.AnswerThe condition is called 'skip'. The waves bounce off the ionisphere and back to earth way past the curvature.
Why does pluto take so long to orbit the earth?
No answer Pluto orbits the Sun Pluto does not orbit the Earth
How do very long radio waves reach stations beyond the curvation of the earth?
Very long radio waves (extremely low frequency) follow the curvature of the earth in a ground wave.Short wave radio waves reflect off the ionosphere and "skip". This is an entirely different effect in a different frequency band. However the two effects are sometimes confused.
What level of atmosphere bounces off radio waves off of the earth?
Radio waves are in all parts of the atmosphere. Some, but not all, radio waves are reflected from the ionosphere, permitting transmission over greater distances.
This layer is responsible for the possibility of radio communication?
The ionosphere is the layer responsible for enabling long-distance radio communication by reflecting radio waves back to Earth. Its charged particles interact with radio waves, bending and reflecting them to facilitate communication over long distances. Without the ionosphere, radio waves would continue into space, limiting long-distance communication possibilities.
Is Radio waves long?
================================================
What layer of the atmosphere do radio waves heading upward from earth often bounce off?
The Ionosphere reflects longer radio waves back to Earth. It varies in height going up at night giving the waves a long distance bounce.Flat vertical walls. Better refraction will Non-ferous metals. Horizontal plan will distort the image of the wave.\ CIV
How long are the years and days in Pluto?
The years in Pluto are 249 Earth years. :) The days in Pluto are 6.4 Earth Days. :)
How far do radio waves travel and what factors affect their range?
Radio waves can travel long distances, sometimes thousands of miles, depending on factors like frequency, power, and obstacles in the environment. The range of radio waves can be affected by interference, atmospheric conditions, and the curvature of the Earth.
