# How long does it take light from the Sun to reach Earth formula?

## How long does it take light from the Sun to reach Earth formula?

Here’s the math. We orbit the Sun at a distance of about 150 million km. Light moves at 300,000 kilometers/second. Divide these and you get 500 seconds, or 8 minutes and 20 seconds.

How do you calculate the time it takes light to travel?

Calculations involving light years and distance – Higher

1. A light year is a distance.
2. It is the distance light travels in one year.
3. As light travels at constant speed, the distance light travels in a year can be calculated using the equation:
4. Distance = speed x time.
5. time = 1 year = 365 x 24 x 60 x 60 = 31,536,000 s.

How many minutes does it take for light to travel from the Sun to the Earth given that the Sun is about 93 million miles from the Earth 1 mile 1.6 km?

On average, the Sun is 150 million kilometers (93 million miles) away from Earth. This means that it takes a photon of light about 8 minutes and 20 seconds to travel from the Sun to Earth.

### How long does it take sunlight to reach Earth Given that the distance to the Sun is 149.6 million km?

The distance between the earth and the sun is 149.6 million kilometres (that’s 92.95 million miles). Scientists calculate that the average time it takes for light to reach the earth from the sun is 8 minutes and 20 seconds.

How are light minutes calculated?

So light can travel 18,000,000 kilometers in one minute! Let’s see how many light minutes Earth is from the Sun. In order to calculate the distance from the Earth to the Sun in light minutes, divide the total distance between the Earth and the Sun by 18,000,000 kilometers or 11,160,000 miles per minute.

How many minutes are required for sunlight to reach Earth if the Sun is 1.50 x10 8 km from Earth?

1 Expert Answer Since speed = distance/time, then time = distance/speed. Remember to convert the distance units to the same unit. Then (1.5×1011 m)/(2.997×108 m/s) = 500 seconds.

## How many minutes does it take the light from the Sun to reach the Earth given that light travels at 186000 miles per second?

Substituting the known values results in 93,000,000 = 186,000*t. So, t = 500 seconds. Divide 500 by 60 to convert to minutes (8 and 1/2 minutes).

Why does light from the Sun take 8 minutes?

The sun is ~92,000,000 miles from earth, and the bullets (photons) travel at 186,000 miles per second, so it takes them about 8 minutes to get here from the surface of the sun.

How long does light take to travel around the Earth?

Earth is 24,901 miles around at its center. If our world had no atmosphere (air refracts and slows down light a little bit), a photon skimming along its surface could lap the equator nearly 7.5 times every second.

### How long does it take light to travel 12 million kilometers?

In 15 seconds, light can travel 4,500,000 kilometers \textbf{4,500,000 kilometers} 4,500,000 kilometers. Light can travel 12 million kilometers in 40 seconds \textbf{40 seconds} 40 seconds.

How did Einstein calculate the speed of light?

It can be derived from Maxwell’s equations that the speed at which electromagnetic waves travel is: c=(ϵ0μ0)−1/2. Since light is an electromagnetic wave, that means that the speed of light is equal to the speed of the electromagnetic waves.

How long does the light take to reach Earth from the Sun which is 1.5 into 10 raise to 11 m away?

8 min
It takes time 8 min for light to reach from the sun to the earth surface.

## How long does it take light to reach us from the Sun 1.50 x10 8 km away?

How do you calculate distance in light minutes?
