Explanation

Light from Sun travels a distance of  150 Million km before it reaches Earth

Distance: ~93 million miles (150 million km) on average.

Speed of Light: ~186,282 miles/second (300,000 km/s) in a vacuum.

Travel Time: Approximately 8 minutes, 20 seconds (or 500 seconds).

Explanation

Studies show that it takes an average of 8 minutes and 20 seconds for sunlight to move from the sun to the earth.

Sunlight moves at the speed of light.

You can see that the distance of the sun from the earth = 149.6 x 106 km.

Photons emitted from the surface of the sun need to traverse the vacuum of the universe to reach our eyes.

Explanation

Wind blows from areas of high pressure to areas of low pressure.

This is because air molecules move from areas of higher concentration (high pressure) to areas of lower concentration (low pressure) to equalize the pressure difference.

This movement of air is what we feel as wind.
