Why is the sea blue?

Question

and also the sky blue???/

Answer 1

The blue colour of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air.

However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue.

The sea appears blue because it is reflecting the sky.

Answer 2

The sea is blue because of the sky.

The sky is blue partly because air scatters short-wavelength light in preference to longer wavelengths. Combined, these effects scatter (bend away in all directions) some short, blue light waves while allowing almost all longer, red light waves to pass straight through. When we look toward a part of the sky not near the sun, the blue color we see is blue light waves scattered down toward us from the white sunlight passing through the air overhead. Near sunrise and sunset, most of the light we see comes in nearly tangent to the Earth's surface, so that the light's path through the atmosphere is so long that much of the blue and even yellow light is scattered out, leaving the sun rays and the clouds it illuminates red.

Answer 3

the colour of the sea mainly reflects the sky

Answer 4

For the same reason the sky is blue. In the spectrum, blue stands out the most when the light reflects.

Answer 5

To know the answer to this question, you must first understand that sunlight is made up of different colours, from red, orange and yellow to green and blue. When sunlight falls on the sea, it is the colour blue that is reflected by the water most easily, giving the sea its blue colour.

Near the coast, sea water takes on a yellow or brownish tinge. This is due to the mud that rivers discharge into the sea, and the vast number of tiny plants and animals near the surface. When clouds hide the sun, the sea will look grey. Weather conditions can also change the colour of the sea.

Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

Answer 6

Because of the way that light is reflected of of iut. The radiation gets bent so our eyes see blue. In reality they are all colourless.
