Why is it that when you look at the sea on a sunny day, it is blue and white, and when you look at it on a cloudy day, it is muddy and yellow?
? We have all seen photos of the earth taken from space. We can see that this is a blue planet, especially beautiful white clouds. Because the ocean is blue, the earth seen in space is also blue, so why is the ocean blue?
? The reason of light is that light on the earth is the source of energy on the earth. It is the energy produced by the fusion of the sun and transmitted to the earth through light. This is a kind of energy, and it is the source of everything on earth. Light cannot see color, but it has color. Rainbow is the color that refracts sunlight. We saw it. Red, orange, yellow, green, blue and purple are the colors of light. Prisms study the color of light. So the sun is blue.
? In sunny weather, you will see the blue sea and blue sky. The sun shines on the sea, soft and bright, with light waves and microwaves. The blue sea is boundless, white clouds float in the sky, seagulls fly happily, fishing boats return with the joy of harvest, and farms float off the coast. This is a beautiful and charming ocean
? When it is cloudy or rainy, there will be northeast wind or east wind on the sea. Except for the wind direction in thunderstorm season. At this time, the sea surface will gradually set off waves, and the undulating sea surface will push the submarine to undercurrent and swell. By then, seabed sediments and microorganisms will be discovered. In addition, if there is no bright sunshine on cloudy days, the sea water will become turbid.
? The weather at sea will change with the weather. Especially when there is heavy rain, the sea water will produce waves, especially the action of sea sand in shallow water will become turbid waves. In deep water and reef areas, due to the lack of sediments, waves are generally blue and white.
? But on the muddy beach, where there are big waves and cloudy days, especially where rivers and sewage enter Haikou, it will be a dark and muddy sea, which is very ugly and suddenly loses its beauty. The sea is like this. According to the intensity of light, the depth of seawater, algae and microorganisms, seawater will have different colors!
