How long does it take a radio signal from the Voyager spacecraft to reach Earth if the distance between Voyager and Earth is 4.16 109 km?

The speed of light is about 300,000 km/sec. Just divide the distance by the speed of light. The answer will be in seconds; divide by 60 to get minutes, by 3600 to get hours, or by 86400 to get days.


How long does it take a radio signal from the Voyager spacecraft to reach Earth if the distance between Voyager and Earth is 3.03 109 km?

Distance = 3.03 x 109 kmSpeed of radio = 3 x 108 m/s = 3 x 105 km/sTime = (distance)/(speed) = (3.03 x 109)/(3 x 105) = 1.01 x 104 seconds = 2hrs48.3min (rounded)


The Voyager 1 spacecraft is currently about 18.5 billion km from the Earth. How long does it take in seconds for a radio signal to get from Voyager 1 to Earth?

That distance you gave is nearly 200 astronomical units so if that is right the time would be 8 minutes times 200, which is 26½ hours.


The space craft that flew by and photographed the four gas giants in the 1970's?

That was the Voyager I and II spacecraft. Voyager I is 10 billion miles away from the sun (the Earth is only ~93 million miles from the sun and Pluto is 3.67 billion miles). A radio signal from Voyager takes ~15 hours to reach Earth.

1.A certain spacecraft is 3.3 AU (Astronomical Units) from Earth. How long in seconds does it take for a signal to reach the Earth after it is transmitted from the spacecraft Hint An AU is about 149.9?

One AU, the distance from the Earth to the Sun, is 500 light-seconds. A signal to a spacecraft at a distance of 3.3 AU would take 500 x 3.3 = 1,650 seconds, or 27.5 minutes.

What happens to the distance between the crests when the amplitude is increased?

Nothing happens. Distance between crests is a measure of frequency; amplitude is a measure of the strength, the height of the wave, or auditory volume of the signal.
