Why sea looks blue?

Answer 1

the sea looks blue as it reflects the colour off the sky;which is blue.

in actual fact, the sea-or any water-has no colour of its own

so if the sky was green, the sea would appear green too...

why the sky is blue... dont ask me!

Answer 2

"The ocean looks blue because red, orange and yellow (long wavelength light) are absorbed more strongly by water than is blue (short wavelength light). So when white light from the sun enters the ocean, it is mostly the blue that gets returned. Same reason the sky is blue."

In other words, the color of the ocean and the color of the sky are related but occur independently of each other: in both cases, the preferential absorption of long-wavelength (reddish) light gives rise to the blue. Note that this effect only works if the water is very pure; if the water is full of mud, algae or other impurities, the light scattered off these impurities will overwhelm the water's natural blueness.
the ocean reflects the blue spectrum of light and absorbs red.

Answer 3

It's reflecting the blue sky. In other words, the color of the ocean and the color of the sky are related but occur independently of each other: in both cases, the preferential absorption of long-wavelength (reddish) light gives rise to the blue. Note that this effect only works if the water is very pure; if the water is full of mud, algae or other impurities, the light scattered off these impurities will overwhelm the water's natural blueness.

Answer 4

Sea water is intrinsically blue. The thicker the observed sample is, the bluer it looks. In smaller water basins, like tap water bath's and Swimming Pools, water appears colorless.

Related Information:

The blue color is caused by selective absorption of infrared spectrum of the sun light.

Water doesn't derive its color from the blue sky. However, without sunlight water can't be seen as blue.

Impurities dissolved or suspended in water may give water different colored appearances, which is more often the case in sea water and lower lakes (greyish brown) than is ice lakes higher in the mountains (blue).

Answer 5

The sea appears blue because water absorbs colors in the red part of the light spectrum, allowing only blue light to be reflected back to our eyes. This gives the sea its characteristic blue hue. Additionally, the reflection of the sky's blue color onto the water also contributes to its blueness.

Answer 6

The water is not blue it's just that the reflection of the sky makes the water look blue.

Answer 7

It depends on the on the layout of the water if its dirty it is black if it has sand Its clear and if it has seaweeds its Blue.

Answer 8

because the sky is blue
