Water becomes blue when it is in large quantities, absorbing colors in the red part of the light spectrum and reflecting blue. This effect is more visible in deeper or larger bodies of water, such as oceans and lakes.
FAQs & Answers
- Why does the ocean appear blue? The ocean appears blue because water absorbs colors in the red part of the light spectrum and reflects the blue light, especially in deeper waters.
- At what depth does water start looking blue? Water begins to look blue at depths greater than 30 feet, where the absorption of red light becomes more significant.
- Do all bodies of water look blue? Not all bodies of water appear blue; factors like depth, sediment, algae, and surrounding landscapes can alter the perceived color of water.
- Can water appear other colors? Yes, water can appear green, brown, or even red depending on factors like algae growth, sediments, or pollutants present in the water.
