How do you work out how long radio waves take to get from Earth to Pluto?

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 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.
How long does it take to get to Neptune from Pluto?
It takes about 7 Monthes to get to Pluto from earth
How long is Pluto's month?
a month on pluto is 248 earth days
Is Earth's day longer than Pluto's day?
No. The day on slowly-rotating Pluto is about 6.4 Earth days long.
How long is Pluto's orbit?
It takes Pluto 247.9days to orbit the sun.
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.
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.
Why does pluto take so long to orbit the earth?
No answer Pluto orbits the Sun Pluto does not orbit the Earth
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. :)
Why are short-waves used in long distance broadcasrs?
Long-distance radio waves are particularly affected by the E and F layers of Earth's ionosphere, causing them to be refracted and reflected back to Earth at a much farther distance or range than they would travel along the Earth's surface. The Earth's surface often reflects the radio waves back up to the ionosphere, where they are again refracted and reflected back to Earth, adding another large distance to their range
