Why would it take long for alpha centauri light to reach earth?
along long long long time
How long would take light to travel from earth to mars at a distance of 56 million km?
At a distance of 56 million kilometers, light requires 3.1 minutes to reach Mars from Earth.
How fast would you have to travel in order to reach a star that is 50 light years away from Earth when you are 40 years older than you were when you left earth?
You would have to be travelling faster than the speed of light in order to do this. And, theoretically speaking, this would be impossible to do.However, if you were possible to travel faster than the speed of light, you would need to be travelling 1.25x the speed of light (which is about 3.75 x 108 m/s2).
Why are UV rays invisible?
UV rays are part of electromagnetic spectrum just like light. Some rays can be detected by the eye and some cant. The sunlight we see is the visible part of this spectrum that is why it is called visible light. Initially only light would reach the earth but now because of ozone depletion even UV rays reach the earth. So basically they are invisible because they are not part of visible light.
If you traveled at the speed of light how long would it take you to reach earth's nearest star?
Actually, the closest star to Earth is Sun which would be reached in a little more than 8 minutes.As for other stars, closest one is Proxima Centauri. You'd need to travel for 4 years and 2 months to reach it at the speed of light. You may or may not know that you have asked a delightful trick question. If I were traveling at the speed of light [impossible, of course] how long would it take me to get to earth's nearest star? From my point of view, the trip would be instantaneous. It would also be an instantaneous trip if I traveled to a destination 100 million light years away. Time completely stops at light speed. Observers on earth would conclude that the trip took me 8 minutes. We would all be right, within the scope of our individual frames of reference.
How long would it take the light from a star 72 light year away from earth to reach the earth?
Easy answer: it would take 72 years.
How many hours would it take for light from Pluto to reach earth?
8 hours
How long would it take light from the sun to reach planet earth?
approximately 8.33seconds
How many meters per second would it take stars light to reach earth?
Light travels at about 300,000 metres per second. The time taken for that light to reach us would depend on the stars distance.
How many years would it take for the Northern Star light to reach Earth?
Polaris (North Star) is about 433 light years from us, so that is how long light will take to reach us.
How much time would moon light needs to reach earth?
Approximately 1.5 seconds.
How does the earth go 150 million km everyday to reach the sun?
the earth does not go to the sun or else we would all be burnt to ashes. it takes about 8 minutes for the light from the sun to reach the earth.
What do light rays need to travel through space?
If light rays did not travel through space there would be no way for them to reach Earth.
How long does it take for energy released by sun to reach earth?
That would depend on which type and form of energy you are referring to. Light energy takes about 8 minutes to reach Earth from the Sun.
How long would a sudden light burst from the galaxy center take to reach earth?
25,000 years.
How long would it take gamma rays from an exploding star to reach earth?
Gamma rays are a form of electromagnetic radiation, and thus they travel at the speed of light. If a star is one light year away, it will reach Earth in one year.
How come the moon reflects the suns light and things on earth dont reflect the suns light?
The moon reflects the suns light and things on the eart do notreflect it because it is at an angle in which the light does not reach earth. So if the light falls on the earth at night there would be light but because it not reflect it on earth it is dark at night.
