Explanation:
The sun is the closest star to the earth and is the primary source of energy for all living organisms on earth. The light from the sun takes some time to reach the earth. The distance between the sun and the earth is constantly changing because both the earth and the sun are moving in their orbits.
Time taken by light to reach the earth:
The speed of light is approximately 299,792,458 meters per second in a vacuum. Using this speed, we can calculate the time taken by light to reach the earth from the sun.
- Distance between the sun and the earth is approximately 149.6 million kilometers.
- Speed of light is approximately 299,792,458 meters per second.
To calculate the time taken by light to reach the earth, we can use the following formula:
Time = distance / speed
Plugging in the values, we get:
Time = 149.6 million kilometers / 299,792,458 meters per second
Time = 499.004 seconds (approximately)
Converting seconds to minutes and seconds, we get:
Time = 8 minutes and 20 seconds (approximately)
Therefore, the correct answer is option 'A' - 8 minutes and 20 seconds.
Conclusion:
The light from the sun takes approximately 8 minutes and 20 seconds to reach the earth. This is an important concept in astronomy and helps scientists understand the behavior of the sun and the earth.
