On today's show, we talk about the colors of the water you see in oceans and lakes. When you cup some of the water in your hand, it's colorless . . . On the other hand, much of the blue color you see comes from the water's depths.
White sunlight contains all colors.
And water absorbs some of these colors more than others. In a large body of water, the water molecules quickly absorb red light, but they don't absorb blue light nearly as well. So muddy water looks brown. What's more, the ocean often looks gray on a stormy day. For today, that's our show.
