9/17/2023 0 Comments Example of transmission lightMeanwhile, muddy waters appear green or even brown because of how little light they leave to scatter. Because blue and green visible light penetrate water better than the shorter and longer wavelengths that flank them, clear water appears blue to us. The suspended particles that affect water’s turbidity absorb light, which allows more light to pass through clearer water. Water clarity, or turbidity, varies within the oceans and across bodies of water, and that affects how light passes through. Conversely, we also know about the Mississippi River, which we call “the Big Muddy” for very good reasons. We’ve seen pictures of the crystal-clear blue waters of the Caribbean Sea-or even seen them firsthand. Water’s index of refraction is 1.333, indicating that it slows down the transmission of light considerably-but less so than plate glass at 1.5 or a diamond at 2.4. The index of refraction of atmospheric air is close to 1 (only a vacuum is exactly 1). We measure this by assigning water an index of refraction. Water slows the transmission of light, which causes the rays to bend. Water does two things to visible light: it reflects some rays and bends, or refracts, others. Here we’ll examine some of the properties of light in water and how we measure that light. When you’re working with lights, it can be important to know about light transmission in the ocean and other bodies of water-how it reflects, refracts, and otherwise behaves as it passes through. They’re deeply unpleasant to think about, so let’s step back.Ībove the benthic deep, light still travels through water, but not the way it does on land. That’s where we find those very strange fish that live their entire lives in the dark. As we go deeper and deeper into the water, we reach a stratum that even sunlight doesn’t reach. The vastness of the ocean has fascinated human beings for years.
