The answer is right there in the words of the question.
Radio and light are the same physical phenomenon, and they travel at the same speed.
The star is 5 light years away. That means the distance that light ... and radio ... travel
in five years.
It takes light from the star 5 years to reach us, and it takes radio from us 5 years to reach
the star.
It takes light around 8 minutes and 19 seconds to reach the earth from the sun.
8 minutes.
The light takes about 640 years to reach Earth, as Betelgeuse (a red supergiant star) is about 640 light years from Earth.
4.37 years. the star is Alpha Centauri ---- That's wrong. The closest star is the sun and it takes 8.3 minutes for light to reach us. when phrased nearest star it can be a trick question.. Alpha Centauri is the nearest star besides the Sun.
Because it only takes 8 minutes for sunlight to reach Earth, but it takes 4 hours to reach Neptune.
It takes light 42.2 years for light from Capella to reach us
It takes approximately 8 minutes for the Sun's light to reach Earth.
If you mean light from the Sun, then it takes eight minutes for the light to reach the Earth.
If the message is sent by radio, then it takes 6 years to reach you.If by USPS, then somewhat longer.
light takes about eight minutes
It takes sunlight about 27 years to reach Vega.
The speed of light is 186,000 miles per second or 300,000 kilometers per second. It takes sunlight about 13 minutes to reach Mars. It takes about 81/2 minutes to reach Earth.
It takes light around 8 minutes and 19 seconds to reach the earth from the sun.
light from the sun
About 37 years.
8 minutes.
