Blue sea

Hi friends it’s time for me to ask you a small question… The Question is “Why the sea appears blue?”

If you don’t know, I’m ready to give you the answer. There are 2 reasons for the sea to appear blue.

The sea reflects the sky.

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.

The sea refracts light

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.

Ok now your doubt is cleared, right! See you guys later, Bye……
