You cannot see any object unless light from that object gets into your eyes .Some of the things you see give off light of their own .The sun ,the stars and a lighted lamp are the examples that can be seen by their own light .Such things are luminous .Most of the things you see are not giving off light of their own .They are simply reflecting light that falls on them from the sun or some other luminous body .The moon ,for example ,doesn't give off any light of its own .It is nonluminous .You see it because sunlight falls on it and some of it reflects in our direction .So moonlight is only second-hand sunlight .
When you look at a book ,it sends some of the light which falls on it to your eyes .and you see the book .If light could be kept out from where you are so that there would be no light from the book to reflect ,then you could not see the book even with your eyes widely open .Light travels so fast that the time in which it travels from the book you are reading to your eyes is as short as if there were no time at all .Light reaches us from the moon ,which is about 380,000 kilometers away ,in only a little more than a second .

除非有来自于物体上的光到达你的眼睛,否则你是看不见任何物体的.有些物体自身可以发光.太阳,星星以及灯就是那些可以自己发光的例子.这些东西是发光的.大多数你看到的东西是不会自己发光的.他们仅仅是将照射到他们上面的来源于太阳或其他发光体的光反射了.例如,月亮是不能自己发光的.它是不发光体.你能看见它是因为日光照在上面,然后其中的一部分朝着我们的方向反射了.所以月光其实只是一种二手的光.当你看书的时候,它将一些落在其上的光送入你的眼中,于是你就看见书了.如果光能到达你所在的地方时被阻碍,那么就没有有光从书上反射,此时你也就看不见书了,即使你的眼睛睁得再大.光传播地如此之快以至于它从你正在看的书传播到你的眼睛所用的时间短的近乎没有.光从离我们380000千米之外的月球射向我们也仅需要一秒多一点.
