海水是无色、透明的。然而,为什么人们总是用“蔚蓝色”来描写和形容海洋呢?的确,当你乘坐飞机掠过海洋而向下俯瞰的时候,所见茫茫海面正是湛蓝碧绿。奇怪的是蓝色从何而来?如果你去做一个小小的实验,也许多少会明白其中的一些道理。 Sea water is colorless and transparent. However, why do people always describe and describe the sea as “blue?” Indeed, as you fly down the ocean and look downwards, the vast sea you see is blue and turquoise. Strange is the blue come from? If you do a little experiment, maybe a few will understand some of them.
