Water appears blue primarily because it absorbs colors in the red part of the light spectrum. Much of the red, orange, and yellow light is absorbed, leaving more blue light to be scattered back to our eyes. This phenomenon occurs because water molecules have a tendency to absorb more red light, similar to how the sky looks blue due to the scattering of sunlight.
FAQs & Answers
- Why does ocean water appear blue? Ocean water appears blue because it absorbs colors in the red part of the light spectrum while scattering blue light back to our eyes.
- What colors of light does water absorb? Water primarily absorbs red, orange, and yellow light, allowing blue light to be more prominently reflected and scattered.
- Does the depth of water affect its color? Yes, deeper water typically appears bluer because more light is absorbed, with only blue wavelengths reflecting back to the surface.
- How does the sky's color relate to why water looks blue? The sky appears blue due to the scattering of sunlight, similar to how water absorbs red light and scatters blue light, creating that blue appearance.
