why do ew see the sky and sea blue?

Question

i know light spectrum (red fades . blue is some how concentrated) but how ?

Answer 1

The blue color 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.
You have probably noticed that the sea is not very blue-looking when the sky is overcast. Water reflects and scatters the light that strikes it; this is shown by the fact that you can see your reflection in puddles. When the sky is brilliant blue, the sea is also, because it reflects the blue of the sky. Blue light is more easily bent, or refracted, than red light; thus, light refracted back from the surface of the sea appears blue. Furthermore, when you are underwater the water around you appears blue because more blue light is scattered back to your eye than red light. Hope that answers the question.

Answer 2

We see the sky as blue cause of refraction of light in the atmosphere. And the sea is blue as it s just a reflection from the sky!

Hope this has enlightened you!

Answer 3

The gasses that make up our atmosphere are blue in thick enough concentrations....You are looking through miles of it when you look up.

The ocean just reflects that...Depending on algae growth, the water may seem more green. Shallow, clear water on light colored sand makes for the nicer blues.

Answer 4

i think it is due to dispersion of light.
