Speed of light

Just like the speed of sound is very fast, the speed of light is even faster!
The speed of sound is 760 miles per hour.

The speed of light is over 670 MILLION miles per hour!

So when you turn on that flashlight, the light goes out from the light bulb so fast that no boat, car or airplane can go faster.

When the sun shines, it is very far away, but it takes eight minutes for a ray of sunshine to hit earth going at the speed of light!
