The distance from the sun to Earth is 1.496×10⁸ km. How long does it take light to travel from the sun to Earth?

검증된 단계별 안내

First, we need to know the speed of light, which is approximately 3.00 * 10^8 meters per second (m/s).

Next, convert the distance from the sun to Earth from kilometers to meters. Remember that 1 kilometer is equal to 1000 meters.

Then, use the formula for time, which is distance divided by speed. In this case, the distance is the distance from the sun to Earth (in meters) and the speed is the speed of light.

Substitute the values into the formula and calculate the time.

Finally, convert the time from seconds to minutes if necessary. Remember that 1 minute is equal to 60 seconds.

Speed of Light

The speed of light in a vacuum is approximately 299,792 kilometers per second (km/s). This constant is crucial for calculating how long it takes light to travel a given distance, such as from the sun to Earth. Understanding this speed allows us to relate distance and time in the context of light travel.

Distance and Time Relationship

The relationship between distance, speed, and time is described by the formula: time = distance/speed. In this scenario, the distance from the sun to Earth is known, and by using the speed of light, we can determine the time it takes for light to cover that distance. This fundamental concept is essential for solving problems involving motion.

Units of Measurement

In physics and chemistry, it is important to use consistent units of measurement. In this case, the distance is given in kilometers, and the speed of light is in kilometers per second. Ensuring that both measurements are in compatible units is necessary for accurate calculations, as it allows for straightforward application of the distance and time relationship.
