Why Is the Sky Blue?

Why Is the Sky Blue? Betty is a smart little gil. She is always asking questions. “ Mommy, why is the sky blue?” Betty asks. Little Betty really wants to know the answer. " Why is it not red or green?Why is it not black or white?Why, Mommy?Why is the sky blue?" Betty's mom looks at her daughter. The answer is not easy to understand. But she tries to explain it in the simplest way possible. She says, " The sun gives off light that has all the colours of the rainbow in it—red, orange, yellow, green, blue, and violet.

为什么天空是蓝色的? 贝蒂是一个聪明的小女孩。她总是问问题。“妈妈，为什么天空是蓝色的?”贝蒂问道。 小贝蒂真的很想知道答案。“为什么它不是红色或绿色的?”为什么不是非黑即白?为什么,妈妈?为什么天空是蓝色的?” 贝蒂的妈妈看着她的女儿。答案并不容易理解。但她试图用最简单的方式解释。 她说:“太阳发出的光有彩虹的所有颜色——红色、橙色、黄色、绿色、蓝色和紫色。

She continues, " When the light travels to earth, it meets the small particles in the air. The light bounces off these particles and spreads the different colours all over the sky. Blue light spreads the most. This is why we see a blue sky. " Betty looks up at the sky. She sees blue. She understands a little now. When she is older, she will understand more.

她继续说:“当光传播到地球时，它会遇到空气中的小颗粒。光线被这些粒子反射，在天空中呈现出不同的颜色。蓝光传播最广。 这就是为什么我们能看到蓝天。”贝蒂抬头看天空。她看到蓝色。她现在有点明白了。当她长大了，她会懂得更多。
