How long does it take for light from the sun to reach earth?
Question
How long does it take for light from the sun to reach earth?
Solution
Light from the Sun takes approximately 8 minutes and 20 seconds to reach Earth. This calculation is based on the average distance between the Earth and the Sun, which is about 93 million miles.
Here's a step-by-step breakdown of how this is calculated:
-
First, we need to know the speed of light, which is approximately 186,282 miles per second (or about 300,000 kilometers per second).
-
Next, we need to know the average distance between the Earth and the Sun, which is about 93 million miles (or about 150 million kilometers).
-
To find out how long it takes for light to travel this distance, we divide the total distance (93 million miles) by the speed of light (186,282 miles per second).
-
This calculation gives us the time in seconds. To convert this into minutes, we divide by 60 (since there are 60 seconds in a minute).
So, the calculation would look something like this:
(93,000,000 miles / 186,282 miles per second) / 60 seconds = approximately 8.3 minutes
So, it takes light about 8 minutes and 20 seconds to travel from the Sun to the Earth.
