For water, whether fresh water or seawater, it is clear, but we see it as blue or dark blue. It's because blue light is best scattered in the water. เที่ยวหลีเป๊ะ And it is the light that is absorbed the least when compared to the other two primary colors, green and red.
What is water scattering?
scattering is diffusion of light in water When light energy strikes a particle or water molecule The wavelength of light is more scattered, we will notice that color light more prominently. The absorption part is The disappearance of light energy when light travels into the water. Water molecules are best absorbed by red light. followed by green light When red light and green light are well absorbed These two colors of light are easily lost upon entering the water. So I can see clear water in blue.
This was observed in the water in the pool. Especially the pool that uses white floor tiles. When filling the pool with water, the water will appear blue or blue. เที่ยวหลีเป๊ะ Even though the floor tiles of the pool are white and the water is clear and colorless. The crystal clear waters look azure or azure like swimming pool water. The water in the deep sea that is very far from the land. will be dark blue The waters near the coast have different colors such as light blue, green, brown, red or yellowish.
