The Speed of Light
Light travels at a speed which is about a million times faster than the speed of sound.
In one second, light travels about 300,000 kilometres.
But sound travels only 0.344 kilometres .You can get some idea of this difference by watching the start of a race. If you
Stand some distance(距离) away from the starter, you can see smoke come from his gun
(枪) before the sound reaches your ears.
This great speed of light produces some strange facts. Sunlight takes about 8 minutes to
reach us. If you look at the light of the moon tonight, remember that the light left the moon 1.3 second before they reached you. The nearest star is far away from the earth. The light which you can see from it tonight started to travel towards you four years ago at a speed of nearly 2 million kilometers one minute. In some cases(情况) the light from one of tonight’s starts started on its journey to you before you were born.
If we want to be honest(诚实), we can not say “The stars are shining tonight.” We have to say, “The stars look pretty(漂亮). They were shining four years ago. But their light has only just reached the earth.. ”

( )1.Light speed is about a million times faster than sound speed.
