Period of light travelled from the sun to earth
It takes 8 minutes, 19 seconds for light to travel from
the Sun to the Earth
Explanation:
Here’s the math. We orbit the Sun at a distance of
about 150 million km. Light moves at 300,000 kilometers/second. Divide these
and you get 500 seconds, or 8 minutes and 20 seconds. This is an average
number. Remember, the Earth follows an elliptical orbit around the Sun, ranging
from 147 million to 152 million km. At its closest point, sunlight only takes
490 seconds to reach Earth. And then at the most distant point, it takes 507
seconds for sunlight to make the journey.
