why is the water blue?

Answer 1

Water is faint blue. Although water appears clear in small quanities (like a glass of water), the blue color becomes visible the more water we look through. Thus, deep lakes and seas are bluer than a shallow river.

Other factors can affect the color we see:

1. Particles and solutes can absorb light, as in tea or coffee. Green algae in rivers and streams often lend a blue-green color. The red sea has occasional blooms of red Trichodesmium erythraeum algae.
2. Particles in water can scatter light. The Colorado river is often muddy red because of suspended reddish silt in the water. Some mountain lakes and streams with finely gound rock, such as glacial flour, are tourquise. Light scattering by suspended matter is required in order that the blue light produced by water's absorption can return to the surface and be observed. Such scattering can also shift the spectrum of the emerging photons toward the green, a color often seen when water laden with suspended particles is observed.
3. The surface of seas and lakes often reflect blue skylight, making them appear bluer. [[[ Montana reflection.]]] The relative contribution of reflected skylight and the light scattered back from the depths is strongly dependent on observation angle.

Answer 3

Actually the sky is blue because it is reflecting the color of the water. The water appears blue because of light refraction like through a prism. Water can be any color depending on how the light is refracted. Ever seen red, yellow, green, blue and orange dew on the grass?

Answer 4

Water strongly absorbs infrared radiation. As infrared radiation is next to red-colored light on the EM spectrum, a small amount of visible red light is absorbed as well. This results in pure water appearing slightly blue, when seen in mass quantities such as a lake or ocean. The color of water in practice can vary strongly by containing impurities. Limestone turns bodies of water turquoise, while iron compounds turn it red/brown and copper compounds create an intense blue. Algae commonly colors water green.

Answer 5

Due to RAMAN'S effect. This effect was first identified and explained by Sir C.V. Raman of India. For this he got nobel prize. He is a great scientist in Physics. The light get disperssed by the dust particles in the atmosphere. The blue light is scattered very much to the visible level. This is simply relected by the sea water. Thus the water in the sea emits blue colour.

Answer 6

molecules in the AIR scatter blue light making the sky APPEAR blue,though it isn't, the ocean simply reflects those colors in those molecules. if you are talking about blue seas those are blue mostly due to reflection of glaciers and things. when water appears green it is because of algae.

Answer 7

It's not Blue.
UR seeing the reflection of the sky that makes it appear blue.

Answer 8

It is clear, but it's properties cause it to absorb longer wavelengths of light (red, orange, yellow) and reflect higher frequencies like blue.

Answer 9

The red light is absorbed more than the blue light and/or the blue light is scattered more then red light.

Answer 10

reflection off the blue sky.
