The light of some stars takes millions of years to reach on the Earth. This indicates that the stars are far away from the earth. The sun appears to be very closer to the earth than the other stars. In how much time does sunlight reaches on Earth?
Answers
Answer:
The required answer is The average time it takes for sunlight to travel from the Sun to the Earth is 8 minutes and 20 seconds.
Explanation:
It would take a little more than 8 minutes for you to realize it was time to put on a sweater if the Sun suddenly vanished from the Universe (not that this could actually happen, so don't panic).
Here's how it works. At a distance of about 150 million kilometers, we orbit the Sun. Light travels at a speed of 300,000 kilometers per second. 500 seconds, or 8 minutes and 20 seconds, is the result of dividing these.
This is a typical figure. Remember that the Earth orbits the Sun in an elliptical orbit that ranges from 147 million to 152 million kilometres. It takes only 490 seconds for sunlight to reach Earth at its closest point. After that, it takes 507 seconds for sunlight to travel to the farthest point.
