The light takes about 640 years to reach Earth, as Betelgeuse (a red supergiant star) is about 640 light years from 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.
It takes light around 8 minutes and 19 seconds to reach the earth from the sun.
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
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.
If you mean light from the Sun, then it takes eight minutes for the light to reach the Earth.
it does reach the earth in light energy.
the light speed are very fast so light easily reach on earth
It takes approximately 8 minutes for the Sun's light to reach Earth.
It takes about 8 minutes and 20 seconds for light from the sun to reach the Earth.

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.
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.
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!!
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.
