Why are the sky and sea blue? 1000 2000

This is the effect of the sun's rays being refracted through the atmosphere!

Most people know that the sky is blue, and so is the sea. In fact, the color of seawater is originally pale because of the absorption, refraction and reflection of sunlight by seawater, which reflects the blue light with short wavelength. It's the same as the sky is blue.

Because the blue sky shines into the sea by the refraction of light, the color of the sea is also blue.

When the sun's white light hits the seawater, it takes on a blue color due to the absorption and scattering of the white light.

Because the sun has many colors of light that hit the sea, but the light of other colors is not obvious at all, only the blue light is more reflective, so we only see that the sea is blue, and we don't see other colors.

Because the sea does not absorb enough blue light from the sun's rays, it is the blue we see now.

There are many strange phenomena in nature, for example, on a clear day, when we look up at the sky, we find that it is blue, and it is so blue that it is clear and comfortable, which makes people feel pleasing to the eye, and science has also explained the phenomenon that the sky is blue.

The reason why the sky appears blue is because the atmosphere scatters sunlight. But the sea is blue like the sky, do you know why the sea is blue? Next, let's uncover the mystery of the blue sea, and you will know it after reading it.

The ocean has always been the focus of scientific research, and scientists have been working tirelessly on marine life and the depth of the seabed. Scientists go deep into the seabed to study, but ignore the external manifestation of the sea - the color of the sea, I believe everyone has also discussed this issue.

Why is the water in the ocean blue?

When you come to the beach, the first thing that catches your eye is the endless sea and the whole blue of the sea. The sky is blue, and so is the sea. If you are in the middle of it, you will completely linger in the beautiful scenery of "sky blue, sea blue".

Why does the water in the sea look blue overall? And when you approach and hold the sea water in the palm of your hand, is it transparent? This is due to the depth of the sea water and the color of the sea when it absorbs sunlight.

The depth of the seawater.

As for the depth of the sea, the deepest trench in the world that has been explored so far is the Mariana Trench, which is about 20,000 meters deep, but this remains a mystery. The reason why the ocean is blue is related to the depth of the water and the amount of water. The depth of the ocean is very deep, and although humans can go deep into the sea, the bottom of the sea is not as lit as on land, so the seabed that explorers see is very dark.

Studies have shown that as you get closer to the surface, the bottom of the ocean gets brighter and brighter, as if it were a bright night scene, like a black and blue sky. Therefore, the deeper the sea, the bluer the sea water will appear to people, which can also explain why the sea water held in the palm of the hand is transparent.

The color of seawater when it absorbs sunlight.

When sunlight hits the surface of the sea, the sea selectively absorbs the three primary colors of sunlight – red, yellow, and blue. Of course, seawater absorbs light waves at longer wavelengths, while red broadcast and yellow light waves have wavelengths higher than blue light wavelengths. Therefore, when the sun shines on the surface of the sea, the sea water only absorbs the light waves with long wavelengths, and retains all the blue light waves.

Therefore, the sea water is blue in the eyes of people, and if the water does not absorb red light waves, then the color of the sea water is probably not blue.

The sea is blue because of the refraction of light. Light is composed of seven colors, and when sunlight hits the ocean, the shorter wavelengths of blue and violet light are scattered in all directions when hindered, and only a small part is absorbed by marine surface organisms. The deeper the water, the more blue light is scattered and the bluer it looks.
