The time taken by light to travel from sun to earth is approximately

Options

A. 8 light years
B. 8 seconds
C. 8 minutes
D. 8 hours

Answer

To determine the time taken by light to travel from the Sun to the Earth, we can follow these steps:

### Step 1: Understand the distance from the Sun to the Earth
The average distance from the Sun to the Earth is approximately 93 million miles or about 150 million kilometers.

### Step 2: Know the speed of light
The speed of light in a vacuum is approximately 299,792 kilometers per second (or about 186,282 miles per second).

### Step 3: Calculate the time taken for light to travel this distance
To find the time taken by light to travel from the Sun to the Earth, we can use the formula:

\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]

### Step 4: Plug in the values
Using the average distance (150 million kilometers) and the speed of light (299,792 kilometers per second):

\[ \text{Time} = \frac{150,000,000 \text{ km}}{299,792 \text{ km/s}} \]

### Step 5: Perform the calculation
Calculating this gives:

\[ \text{Time} \approx 500 \text{ seconds} \]

### Step 6: Convert seconds to minutes
Since there are 60 seconds in a minute, we can convert seconds to minutes:

\[ \text{Time in minutes} = \frac{500 \text{ seconds}}{60} \approx 8.33 \text{ minutes} \]

### Conclusion
Thus, the time taken by light to travel from the Sun to the Earth is approximately 8 minutes.

### Final Answer
The time taken by light to travel from the Sun to the Earth is approximately **8 minutes**.
