How many seconds will it take to send a radio signal to Pluto from earth?

Answer 1

there is no sound on the moon or in space, there is no air to vibrate and make sound

But...

Assuming sound could travel from the earth to the moon,

the moon is 3.9x10^8 meters from earth.

Sound travels at 340 meters/second. (or 3.4x10^2)

(3.9x10^8)/(3.4x10^2) = 1.47x10^6 seconds.

In other words, If sound could travel through the vacuum of space, It would take 1,470,000 seconds to travel from the moon to the earth.

This might seem like too much at first, but remember that sound moves like a slug compared to light. Anybody who has watched a fireworks show from across a lake or bay will know firsthand that you can see the light from the firework a fraction of a second before hearing the explosion. This is over a relatively tiny distance. (a few miles), as compared to the vast distance between our planet and moon.

Answer 2

A radio signal takes less than one and one half seconds to reach the moon. The moon orbits an average distance of 384,400 kilometers from Earth and radio waves travel through space at 299,800 kilometers per second.

Answer 3

The distance that light travels in a fixed amount of time is a common way to measure astronomical distances. Thus one has lightseconds, lightminutes, and lightyears.

If you measure the distance from the earth to the moon in terms of the speed of light, it is approximately 1.28 light seconds away.

Thus, it will take about 1.28 seconds for communication from the earth to reach the moon, or communications from the moon to reach earth. A "round trip" communication would take double that, or about 2.56 seconds.

Answer 4

If sound could continue all the way to the moon at the same speed that it typically

has at sea level on earth, it would arrive there after a journey of roughly 13 days.

(384,400 km, 343 m/s)

Answer 5

Depends entirely on the distance between the Earth and Pluto and their respective orbits.

Pluto can be anything from 30 to 50 AU from the Sun.

So at the closest: 29 AU or 241.185854 light minutes or 14,471.1512 light seconds

At the furthest, 51 Astronomical Units = 424.154433 light minutes or = 25,449.266 light seconds

Answer 6

It takes about 4.5 hours (or 16,200 seconds) for a radio signal to travel from Earth to Pluto at the speed of light, which is approximately 186,282 miles per second.

Answer 7

It takes a radio signal about 1.3 second to reach the Moon.

Answer 8

Sound only travels through matter, not through empty space. So sound won't reach the moon, it will stop where the Earth's atmosphere ends.

Answer 9

Sound can not travel through a vacuum, so sound generated on Earth would never reach the Moon.

Answer 10

Radio waves take 2 seconds to travel 600,000 kilometers through vacuum.

The moon, though, is only about 385,000 kilometers from Earth.
