Time taken for light to reach from the earth to the sun
Light travels at a speed of approximately 299,792 kilometers per second (or about 186,282 miles per second). The distance from the Earth to the Sun is about 93 million miles (or 150 million kilometers).
To calculate the time taken for light to travel from the Earth to the Sun, we can use the formula:
Time = Distance / Speed
Calculation
- Distance from Earth to Sun: 93 million miles (150 million kilometers)
- Speed of light: 186,282 miles per second (299,792 kilometers per second)
Using the formula, we can calculate the time taken for light to reach from the Earth to the Sun:
Time = 93 million miles / 186,282 miles per second
Time = 499.11 seconds
Converting seconds to minutes:
Time = 499.11 seconds / 60 seconds per minute
Time ≈ 8.3 minutes
Therefore, it takes approximately 8.3 minutes for light to travel from the Earth to the Sun.
This explains why option 'B' (8.3 minutes) is the correct answer.
