下午散步时，朵朵仰起头问：“妈妈，天空为什么是蓝色的呀？”

On an afternoon walk, Duoduo looked up and asked, "Mama, why is the sky blue?"

下午散步时，朵朵仰起头问：“妈妈，天空为什么是蓝色的呀？”

On an afternoon walk, Duoduo looked up and asked, "Mama, why is the sky blue?"

妈妈说：“阳光看起来是白色的，其实里面藏着彩虹一样的各种颜色呢。”

Mama said, "Sunlight looks white, but it holds all the colors of the rainbow."

“阳光穿过大气层时，会遇到数不清、肉眼看不见的气体分子。”

"As sunlight travels through the atmosphere, it meets countless gas molecules too tiny to see."

“蓝色光的波纹更短，遇到气体分子时，更容易朝四面八方散开。”

"Blue light has shorter waves, so gas molecules scatter it more easily in every direction."

“散开的蓝光铺满天空，所以我们抬头看，到处都是蓝色。”

"That scattered blue fills the whole sky — so everywhere we look, we see blue."

“那傍晚为什么会变成橙红色？”“阳光斜着穿过更多空气，蓝光大多散到四周，橙红光更容易来到眼睛。”

"Then why does sunset turn orange?" "At dusk sunlight crosses more air. Most blue light scatters aside, while orange-red light reaches our eyes more easily."

朵朵眨眨眼睛：“原来天空的颜色，是阳光和空气一起变的魔术！”

Duoduo's eyes sparkled. "So the sky's color is a magic trick by sunlight and air together!"

回家路上，月亮高高挂在前方。朵朵走了几步又回头：“月亮为什么一直跟着我走呢？”

On the way home, the moon hung high ahead. After a few steps, Duoduo looked back. "Why does the moon keep following me?"

太阳光里藏着彩虹般的各种颜色，蓝光的波纹较短，更容易被气体分子散向整个天空。

Sunlight holds all the colors of the rainbow; blue light has shorter waves, so gas molecules scatter it across the sky more easily.
