How long does it take for the light generated by the star Betelgeuse to reach Earth?
The light takes about 640 years to reach Earth, as Betelgeuse (a red supergiant star) is about 640 light years from Earth.
How many years will it take something 8000 light years away to reach earth?
An object that is 8,000 light years away from Earth will take 8,000 years to reach us if it travels at the speed of light. Since nothing can travel faster than light according to our current understanding of physics, this distance would require that same amount of time, 8,000 years, for light (or anything traveling at that speed) to cover the distance to Earth.
How long does it takes the sunlight to reach the Earth?
It takes light around 8 minutes and 19 seconds to reach the earth from the sun.
What takes longer to reach earth light from the sun or light from other stars?
Light from the sun because all light travels at the same speed, and the sun is the closest star to the earth, so therefore the light from the sun reaches the earth before light from other (further away) stars
The nearest star to Earth is Proxima Centauri which is 4.3 light-years away If light leaves this star in 2020 when will it reach Earth?
If light leaves Proxima Centauri in 2020, it will take 4.3 years to reach Earth. Therefore, the light will arrive on Earth in the year 2024.
How does it take for light to reach earth?
If you mean light from the Sun, then it takes eight minutes for the light to reach the Earth.
Does most of suns energy reach earth in light energy?
it does reach the earth in light energy.
How does sunlight reach earth?
the light speed are very fast so light easily reach on earth
How long it takes the suns light to reach earth?
It takes approximately 8 minutes for the Sun's light to reach Earth.
How long does it take for light from the sun to reach the Earth?
It takes about 8 minutes and 20 seconds for light from the sun to reach the Earth.

Does an em wave require medium such as air or water to travel through?
No, electromagnetic waves do not require a medium to travel through. They can propagate through a vacuum, which is why light from the sun can reach the Earth through the vacuum of space.
How does the light from the moon reach the earth?
The moon does not emit light, rather it reflects it. The light from the sun shines on the moon, and it is reflected to earth.
Is a medium necessary for a wave to travel?
No not really. Sound waves are mechanical waves. They require a medium for propagation. On the other hand, Light waves are electromagnetic and do not require a medium. Hence you cannot hear in space. AND light waves reach the earth from the sun through space- which is a vacuum!!
How long will it take the get the suns heat to earth?
It will take 8 minutes for the light from the sun to reach Earth. The actual heat of the sun does not reach all the way out to Earth. The warmth on Earth comes from the conversion of light energy to heat energy.
