雪花落到小米手心，她抬头问：“雪为什么是白色的？”

A snowflake landed in Mimi’s mitten. She looked up and asked, “Why is snow white?”

雪花落到小米手心，她抬头问：“雪为什么是白色的？”

A snowflake landed in Mimi’s mitten. She looked up and asked, “Why is snow white?”

妈妈接住一片雪花：“先看看，这片小冰晶近乎透明。”

Mom caught a snowflake too. “First, look closely. This tiny ice crystal is almost transparent.”

纯净冰晶像小小玻璃，光能穿过它。

A pure ice crystal is like a tiny piece of glass. Light can pass through it.

可是雪不是一片冰晶，而是许多冰晶和空气空隙。

But snow is not one crystal. It is many crystals, with tiny spaces of air between them.

阳光遇到冰晶表面，会反射、折射，并向不同方向散射。

When sunlight meets the crystal surfaces, it reflects, bends, and scatters in many directions.

各种可见光大致一起回到眼睛，雪就显得白。

The visible colors come back toward our eyes together, more or less, so the snow looks white.

小米捧起雪团：“原来不是白色颜料，是光被一起散回来！”

Mimi lifted a handful of snow. “So it isn’t white paint! The light is scattered back together!”

小米又问：“那树叶上的露珠，是怎么来的呢？”

Mimi’s eyes sparkled with a new question: “Then how do dewdrops form on leaves?”

雪由许多冰晶和空气空隙组成，光被反射、折射并向各处散射，各种可见光大致一起进入眼睛，所以雪看起来是白色的。

Many ice crystals and air gaps scatter light in many directions, making snow look white.
